REPRESENTATION Appellant represented by: Disabled American Veterans ATTORNEY FOR THE BOARD Suzie S. Gaston, Counsel INTRODUCTION The Veteran served on active duty from November 1988 to October 1993. This matter comes before the Board of Veterans' Appeals (Board) on appeal from rating decisions by the Department of Veterans Affairs (VA) Regional Office (RO) in Huntington, West Virginia and Louisville, Kentucky. By a rating action in November 2004, Huntington, WV RO denied the claim for a rating in excess of 10 percent for residuals, surgery, left great toe. Subsequently, in a January 2007 rating action, the Louisville, Kentucky RO increased the evaluation for residuals, surgery, left great toe from 10 percent to 20 percent, effective June 3, 2004. By a rating action in July 2007, the RO denied the claims of entitlement to service connection for fatigue, joint pain, muscle pain, respiratory problems, and neurological symptoms, service connection for sleep disorder, vertigo, irritable bowel syndrome and PTSD. A September 2008 rating decision granted service connection for polyarthralgias, rated as 10 percent disabling; service connection as also granted for multi-focal tremors and irritable bowel syndrome, each evaluated as 10 percent disabling. The Veteran perfected a timely appeal to those rating actions. In light of the recent decision of Clemens v. Shinseki, 23 Vet. App. 1 (2009), in which it was determined the scope of a mental health disability claim includes any mental disability that may reasonably be accomplished by the claimant's description of the claim, reported symptoms, and other information of record, the Board considers the Veteran's claim of service connection for PTSD to be as styled on the title page. The issues of entitlement to service connection for an acquired psychiatric disorder to include PTSD and depression, service connection for respiratory problems to include asthma, and increased rating for residuals, surgery, left great toe are addressed in the REMAND portion of the decision below and is REMANDED to the RO via the Appeals Management Center (AMC), in Washington, DC. FINDINGS OF FACT 1. The Veteran had active service in the Southwest Asia Theater of operations during the Persian Gulf War. 2. The Veteran has been diagnosed as having obstructive sleep apnea and his complaints of problems with sleeping and fatigue have been attributed to this condition. 3. The preponderance of the evidence shows the Veteran did not have obstructive sleep apnea during service, or until more than ten years after his discharge, and that the condition is unrelated to his service. 4. The Veteran has been granted service connection for tinnitus based on exposure to acoustic trauma while he was on active duty. 5. An April 2007 VA examiner opined that the Veteran's development of benign paroxysmal vertigo was etiologically related to his tinnitus. 6. Polyarthralgia has not been manifested by objective episodic symptoms with exacerbations precipitated by environmental or emotional stress or by overexertion or being present more than one-third of the time; nor are they constant, or nearly so, and refractory to therapy. 7. The Veteran's multi-focal tremors are manifested by no more than moderate symptomatology. 8. Irritable bowel syndrome is manifested by alternating diarrhea and constipation but there is no reliable evidence that this condition is associated with more or less constant abdominal distress. 9. For the appellate period prior to September 18, 2008, the Veteran's had a Level II hearing loss in his right ear, and a Level I hearing loss in his left ear. 10. Audiometric testing on September 19, 2008 revealed that puretone thresholds at each of the four specified frequencies (1,000, 2,000, 3,000 and 4,000 Hertz) is 55 decibels or more. 11. Using Table VIA, the September 2008 Audiological evaluation reveals the Veteran manifests Level V hearing in his right ear and level VI in his left ear. CONCLUSIONS OF LAW 1. A sleep disorder and fatigue, claimed as obstructive sleep apnea, was not incurred in or aggravated by service; nor is it shown to be due to undiagnosed illness as a result of service in the Southwest Asia theater during the Persian Gulf War. 38 U.S.C.A. §§ 1110, 1117, 1131, 5103(a), 5103A, 5107 (West 2002 & Supp. 2009); 38 U.S.C.A. §§ 3.102, 3.159, 3.303, 3.317 (2009). 2. Giving the benefit of the doubt to the Veteran, benign paroxysmal vertigo is proximately due to or the result of a service-connected disability. 38 U.S.C.A. §§ 1110, 1131, 5103, 5107 (West 2002 & Supp. 2009); 38 C.F.R. §§ 3.102, 3.159, 3.303, 3.310 (2009). 3. The criteria for an initial evaluation in excess of 10 percent for polyarthralgias have not been met. 38 U.S.C.A. §§ 1155, 5103, 5103A, 5107 (West 2002 & Supp. 2009); 38 C.F.R. §§ 3.159, 4.1, 4.7, 4.40, 4.45, 4.59, 4.71a, Diagnostic Codes 8850-5025 (2009). 4. The criteria for an initial rating in excess of 10 percent for multi-focal tremors have not been met. 38 U.S.C.A. §§ 1155, 5103, 5103A, 5107 (West 2002 & Supp. 2009); 38 C.F.R. §§ 3.102, 3.159, 3.321(b), 4.1, 4.2, 4.3, 4.7, 4.10, 4.20, 4.27, 4.124a, DCs 8881-8103 (2009). 5. The criteria for a rating in excess of 10 percent for irritable bowel syndrome have not been met. 38 U.S.C.A. §§ 1155, 5103A, 5107 (West 2002); 38 C.F.R. §§ 3.159, 4.1, 4.7, 4.114, Diagnostic Code (DC) 7319 (2009). 6. For the appellate period prior to September 19, 2008, the criteria for a compensable rating for bilateral hearing loss are not met. 38 U.S.C.A. §§ 1155, 5103, 5103A, 5107 (West 2002 & Supp. 2009); 38 C.F.R. §§ 3.102, 3.159, 4.3, 4.7, 4.85, Diagnostic Code 6100 (2009). 7. As of September 19, 2008, the criteria for a 20 percent rating, but no more, for bilateral hearing loss have been met. 38 U.S.C.A. §§ 1155, 5103, 5103A, 5107 (West 2002 & Supp. 2009); 38 C.F.R. §§ 3.102, 3.159, 4.3, 4.7, 4.85-4.87, Diagnostic Code 6100 (2009). REASONS AND BASES FOR FINDINGS AND CONCLUSIONS I. Duty to Notify and Assist. The Veterans Claims Assistance Act of 2000 (VCAA) enhanced VA's duty to notify and assist claimants in substantiating their claims for VA benefits, as codified in pertinent part at 38 U.S.C.A. §§ 5103, 5103A (West 2002 & Supp. 2009); 38 C.F.R. §§ 3.159, 3.326(a) (2009). Upon receipt of a complete or substantially complete application for benefits, VA is required to notify the claimant of the information and evidence not of record that is necessary to substantiate the claim; and to indicate which information and evidence VA will obtain and which information and evidence the claimant is expected to provide. 38 U.S.C.A. § 5103(a); 38 C.F.R. § 3.159(b). The U.S. Court of Appeals for Veterans Claims has held that VCAA notice should be provided to a claimant before the initial RO decision on a claim. Pelegrini v. Principi, 18 Vet. App. 112 (2004). However, if VCAA notice is provided after the initial decision, such a timing error can be cured by subsequent readjudication of the claim, as in a statement of the case (SOC) or Supplemental SOC (SSOC). Mayfield v. Nicholson, 20 Vet. App. 537, 543 (2006); Prickett v. Nicholson, 20 Vet. App. 370, 376 (2006). In this case, VA satisfied its duty to notify by means of letters dated in August 2004 and January 2007 from the RO to the Veteran which were issued prior to the RO decisions in November 2004, July 2007, and September 2008. Additional letters were issued in May 2008 and November 2008. Those letters informed the Veteran of what evidence was required to substantiate the claims and of his and VA's respective duties for obtaining evidence. The Board finds that the content of those letters complied with the requirements of 38 U.S.C.A. § 5103(a) and 38 C.F.R. § 3.159(b) regarding VA's duty to notify and assist. He was provided an opportunity at that time to submit additional evidence. In addition, the January 2007 SOC, the August 2008 SSOC, the September 2008 SOC, the February 2009 SOC, and the February 2009 SSOC provided the Veteran with an additional 60 days to submit additional evidence. Thus, the Board finds that the purpose behind the notice requirement has been satisfied because the Veteran has been afforded a meaningful opportunity to participate effectively in the processing of his claims. It also appears that all obtainable evidence identified by the Veteran relative to his claim has been obtained and associated with the claims file, and that neither he nor his representative has identified any other pertinent evidence, not already of record, that would need to be obtained for a fair disposition of this appeal. It is therefore the Board's conclusion that the Veteran has been provided with opportunity to submit evidence and argument in support of his claim, and to respond to VA notices. The Board is unaware of any outstanding evidence or information that has not already been requested. Therefore, the Board is satisfied that the RO has complied with the duty to assist requirements of the VCAA and the implementing regulations. Neither the Veteran nor his representative has contended that any evidence relative to the issues decided herein is absent from the record. The Veteran has been afforded examinations on the issues decided herein. McLendon v. Nicholson, 20 Vet. App. 79 (2006). Significantly, the Veteran was afforded examinations in September 2004, April 2007, and September 2008. The reports reflect that the examiners solicited symptoms from the Veteran, examined the Veteran, and provided diagnoses consistent with the record. Therefore, these examinations are adequate. Nieves- Rodriguez v. Peake, 22 Vet. App. 295 (2008). Accordingly, the Board finds that VA has satisfied its duty to assist the Veteran in apprising him as to the evidence needed, and in obtaining evidence pertinent to his claim under the VCAA. Therefore, no useful purpose would be served in remanding this matter for yet more development. Such a remand would result in unnecessarily imposing additional burdens on VA, with no additional benefit flowing to the Veteran. The Court of Appeals for Veterans Claims has held that such remands are to be avoided. Sabonis v. Brown, 6 Vet. App. 426, 430 (1994). II. Factual background. The record indicates that the Veteran served on active duty from November 1988 to October 1993. The Veteran's DD Form 214 indicates that he was awarded the National Defense Service Medal, the Kuwait Liberation Medal, and the Southwest Asia Service Medal with 3 Bronze stars. The service treatment reports, including his November 1988 enlistment examination and July 1993 discharge examination, are completely silent with respect to any complaints, findings or diagnoses of a sleeping disorder. The STRs show that the Veteran suffered fracture of the distal phalanx, left great toe. He was diagnosed with hallux valgus deformity with questionable bunion formation, first metatarsophalangeal joint. On the occasion of an initial VA examination in May 1994, the Veteran was diagnosed with bilateral high frequency hearing loss, more impaired in the left than the right ear. He was also diagnosed with status post bunionectomy and osteotomy of the left great toe, with subjective complaints of continued pain. The Veteran was afforded another VA Audiological evaluation in September 2004. On the authorized Audiological evaluation, pure tone thresholds, in decibels, were as follows: HERTZ 500 1000 2000 3000 4000 RIGHT 20 20 20 50 LEFT 15 30 60 60 Speech audiometry revealed speech recognition ability of 96 percent in the right ear and of 96 in the left ear. The examiner stated that hearing test results revealed normal hearing through 3000 Hz with a moderate sensorineural hearing loss at 4000 Hz in the right ear. For the left ear, there was normal hearing through 1000 Hz with a mild to moderately severe sensorineural hearing loss from 2000 to 4000 Hz. Speech was recognition ability was excellent bilaterally. It was the opinion of the licensed audiologist based on review of the claims file, specifically the information referenced in the review of medical records section, and based on the Veteran's reported history, that his hearing loss in the right ear and his tinnitus are at least as likely as not a result of or aggravated by his noise exposure while in military service. The Veteran was also afforded a VA examination for evaluation of his feet in September 2004. The Veteran indicated that the pain in his left great toe is worse; he stated that he is trying to cope with his great toe during his everyday life with physical activity. He reported constant pain in the great toe of the left foot, as well as stiffness, swelling with prolonged weightbearing, redness, fatigability, and lack of endurance. He is limited with flare-up, in that he has to sit down and get off the foot. He denied the use of a brace or orthotics. He denied the use of external devices. He stated that he tries to stay in a soft shoe. On examination, it was noted that his gait is with a left leg limp. He had a normal longitudinal arch bilaterally with normal Achilles tendon alignment. Heel walk was normal. Tandem walk was slightly unsteady. He had a well-healed first foot left great dorsal metatarsal longitudinal scar. He had normal pedal pulses and posterior tibial pulses. He was able to supinate and pronate without any difficulty. Sensation was decreased to pinprick and soft touch. There was no left great toe deformity or discoloration. There was no atrophy of the feet. Active flexion and hyperextension of the left great toe metatarsophalangeal joint was 0 degrees with attempt. Left great toe passive metatarsophalangeal joint, interphalangeal joint flexion was 30 degrees of the left great toe. Dorsiflexion was 15 degrees with pain. His left great toe range of motion was additionally limited by pain following attempted use with repetitive motion. The pertinent diagnoses were status post left great toe bunionectomy per history, and status post left great toe fusion per history. VA progress notes dated from November 2004 through October 2006 reflect diagnoses of tinnitus, vertigo, hearing loss, gastroesophageal reflux disease and depression. Progress notes in September 2006 reflect diagnoses of tinnitus, vertigo, and hearing loss. A primary care note, dated in October 2006 indicates that the Veteran had an MRI of the brain done for vertigo symptoms; this was normal. The Veteran was afforded a Gulf War examination in April 2007. The Veteran complained of fatigue; he stated that symptoms of fatigue became noticeable in April 1991. The Veteran indicated that many people tell him that he snores loud. He also reported restlessness of his legs. The Veteran also complained of abdominal pain, nausea, diarrhea and bloating, brain fog, shortness of breath with rest, visual disturbances, dizziness, and balance problems. The Veteran reported symptoms of alternation of constipation and diarrhea on a daily basis. He also reported daily abdominal pain with cramping. The veteran stated that he has a bloated feeling at times. The examiner reported a diagnosis of fatigue, by history, with pulmonary sleep study report and evidence of mild obstructive sleep apnea, which is likely the cause of the Veteran's fatigue since this is not treated. Symptom associated with this diagnosis was reported as fatigue. The examiner also reported a diagnosis of bilateral knee and elbow pain by history. Symptoms associated with this diagnosis were pain and stiffness. Another reported diagnosis was irritable bowel syndrome. The examiner noted that the Veteran's service treatment records with abdominal complaints were associated with a diagnosis of peptic acid disease. The effect of this disease is that the Veteran has to constantly go to the bathroom and it could be sudden. The examiner also reported a diagnosis of myofascial pain by history. A respiratory condition by history. There was no current medical evidence to demonstrate a disability. Tremors by history; there were no current medical evidence to demonstrate a disability. The Veteran reported a diagnosis of mild obstructive apnea. On the authorized Audiological evaluation in April 2007, pure tone thresholds, in decibels, were as follows: HERTZ 500 1000 2000 3000 4000 RIGHT 30 30 25 55 LEFT 20 35 65 65 Speech audiometry revealed speech recognition ability of 88 percent in the right ear and of 92 in the left ear. The examiner noted that the Veteran had normal to moderately severe sensorineural hearing loss in the right ear and normal to moderately severe sensorineural hearing loss in the left ear. The examiner stated that, based upon discussion with the Veteran regarding vertigo, stated as secondary to his tinnitus, is related to military service. On the occasion of another authorized Audiological evaluation in September 2008, pure tone thresholds, in decibels, were as follows: HERTZ 500 1000 2000 3000 4000 RIGHT 55 60 70 75 LEFT 55 65 85 85 Speech audiometry revealed speech recognition ability of 72 percent in the right ear and of 80 in the left ear. (average 65 dc in the right and 72.5 in the left). The pertinent diagnoses were moderate to severe sensorineural hearing loss in both ears. The examiner stated that the test results were of poor consistency and were not felt to be a true representation of the Veteran's hearing ability. The examiner was also afforded a Gulf War examination in September 2008. The examiner noted that the Veteran has been evaluated by a neurologist who defined his complained of generalized joint and muscle pain as polyarthralgias, and has suggested Tylenol arthritis medication which has been helpful in improving his symptoms. The rheumatologist did not suggest the possibility of fibromyalgia. The Veteran indicated that he has had problems with unexplained tremors, which seems most pronounced in his right hand. The Veteran indicated that the problem is most embarrassing since it can last 30-45 minutes; he tries to eat, he cannot hold any food. The Veteran indicated that he used to have extreme cramps of the stomach; after the cramping was present for several minutes to 10 minutes or so, he would get the feeling that diarrhea was coming on, and he would have to get to the bathroom. The Veteran indicated that he has currently started treatment with medications to calm his stomach, and bowels and has done much better. His incidence of cramping and diarrhea are very infrequent. The Veteran also indicated that he has been treated for vertigo and dizziness for many years; he noticed that this started after he was on active duty. Following an evaluation, the examiner reported diagnosis of polyarthralgias, associated with generalized joint and muscle pain. The examiner also reported a diagnosis of multi-focal tremors, which causes decreased manual dexterity. The examiner stated that he did not feel that an EMG/NCV were appropriate since the situation occurs at unknown intervals, and does not cause paralysis, or loss of function. Irritable bowel syndrome; he noted that the Veteran was doing well with his symptoms; when they do occur, he experiences severe cramping of the abdomen. The examiner also reported a diagnosis of benign paroxysmal vertigo. III. Legal analysis-Service Connection. An award of service connection is warranted for a disability "resulting from personal injury suffered or disease contracted in line of duty, or for aggravation of a preexisting injury suffered or disease contracted in line of duty." 38 U.S.C.A. §§ 1110, 1131. To establish a right to compensation for a present disability, a Veteran must show: "(1) the existence of a present disability; (2) in-service incurrence or aggravation of a disease or injury; and (3) a causal relationship between the present disability and the disease or injury incurred or aggravated during service"--the so-called "nexus" requirement. Shedden v. Principi, 381 F.3d 1163, 1167 (Fed. Cir. 2004). Holton v. Shinseki, 557 F.3d 1362 (2009). In addition, the law provides that, where a Veteran served ninety days or more of active military service and an organic disease of the nervous system becomes manifest to a degree of 10 percent within one year from the date of termination of such service, such disease shall be presumed to have been incurred in service, even though there is no evidence of such disease during the period of service. 38 U.S.C.A. §§ 1101, 1112, 1113, 1137; 38 C.F.R. §§ 3.307, 3.309. While the disease need not be diagnosed within the presumption period, it must be shown, by acceptable lay or medical evidence, that there were characteristic manifestations of the disease to the required degree during that time. Id. For a showing of chronic disease in service, there is required a combination of manifestations sufficient to identify the disease entity, and sufficient observation to establish chronicity at the time, as distinguished from merely isolated findings or a diagnosis including the word "chronic." Continuity of symptomatology is required where the condition noted during service is not, in fact, shown to be chronic or where the diagnosis of chronicity may be legitimately questioned. If the fact of chronicity in service is not adequately supported, then a showing of continuity after discharge is required to support the claim. 38 C.F.R. § 3.303(b) (2009). Service connection may also be established for disability that is proximately due to or the result of a service- connected disease or injury. 38 C.F.R. § 3.310(a) (2006); See Harder v. Brown, 5 Vet. App. 183, 187 (1993). Prior to October 10, 2006, the provisions of 38 C.F.R. § 3.310 directed, in pertinent part, that: Except as provided in § 3.300(c), disability which is proximately due to or the result of a service- connected disease or injury shall be service-connected. When service connection is thus established for a secondary condition, the secondary condition shall be considered a part of the original condition. The Court clarified that service connection shall be granted on a secondary basis under the provisions of 38 C.F.R. § 3.310(a) where it is demonstrated that a service-connected disorder has aggravated a nonservice-connected disability. Allen v. Brown, 7 Vet. App. 439 (1995). The term, "disability", as contemplated by the VA regulations, means "impairment in earning capacity resulting from . . . [all types of] diseases or injuries [encountered as a result of or incident to military service] and their residual conditions. . . ." 38 C.F.R. § 4.1 (1990). Pursuant to § 1110 and § 3.310(a), when aggravation of a Veteran's non-service-connected condition is proximately due to or the result of a service-connected condition, such Veteran shall be compensated for the degree of disability (but only that degree) over and above the degree of disability existing prior to the aggravation. Cf. 38 C.F.R. § 3.322 (1994) (in compensating for aggravation of a preservice disability by active service, it "is necessary to deduct from the present evaluation the degree, if ascertainable, of the disability existing at the time of entrance into active service, in terms of the rating schedule . . ."). Allen v. Brown, 7 Vet. App. 439 (1995). The amendment of October 2006 to 38 C.F.R. § 3.310 sets a standard by which a claim based on aggravation of a non- service-connected disability by a service-connected one is judged. Although VA has indicated that the purpose of the regulation was merely to apply the Court's ruling in Allen v. Brown, 7 Vet. App. 439 (1995) (which allowed for secondary service connection on an aggravation basis), it was made clear in the comments to the regulation that the changes were intended to place a burden on the claimant to establish a pre-aggravation baseline level of disability for the non- service-connected disability before an award of service connection based on aggravation may be made. This had not been VA's practice, which strongly suggests that the recent change amounts to a substantive change in the regulation. Given what appear to be substantive changes, and because the veteran's claim was pending before the regulatory change was made, the Board will consider the version of 38 C.F.R. § 3.310 in effect before the change, which version favors the claimant. 38 C.F.R. § 3.310 (2009). Service connection may be granted to a Persian Gulf veteran who exhibits objective indications of chronic disability resulting from an undiagnosed illness or a medically unexplained chronic multi-symptom illness (such as chronic fatigue syndrome, fibromyalgia, and irritable bowel syndrome) that is defined by a cluster of signs or symptoms, or resulting from an illness or combination of illnesses manifested by one or more signs or symptoms such as those listed below. The symptoms must be manifest to a degree of 10 percent or more during the presumptive periods prescribed by the Secretary or by December 31, 2011. By history, physical examination and laboratory tests, the disability cannot be attributed to any known clinical diagnosis. Objective indications of chronic disability include both "signs" in the medical sense of objective evidence perceptible to an examining physician, and other, non-medical indicators that are capable of independent verification. Disabilities that have existed for 6 months or more and disabilities that exhibit intermittent episodes of improvement and worsening over a 6-month period will be considered chronic. The signs and symptoms which may be manifestations of undiagnosed illness or a chronic multi-symptom illness include, but are not limited to: (1) fatigue, (2) signs or symptoms involving the skin, (3) headaches, (4) muscle pain, (5) joint pain, (6) neurologic signs or symptoms, (7) neuropsychological signs or symptoms, (8) signs or symptoms involving the respiratory system (upper or lower), (9) sleep disturbance, (10) gastrointestinal signs or symptoms, (11) cardiovascular signs or symptoms, (12) abnormal weight loss, or (13) menstrual disorders. 38 U.S.C.A. §§ 1117, 1118 (West 2002); 38 C.F.R. § 3.317 (2009). The Veteran can attest to factual matters of which she had first-hand knowledge, e.g., experiencing pain in service, reporting to sick call, being placed on limited duty, and undergoing physical therapy. See Washington v. Nicholson, 19 Vet. App. 362, 368 (2005). However, the veteran as a lay person has not been shown to be capable of making medical conclusions, thus, her statements regarding medical causation are not competent. Espiritu v. Derwinski, 2 Vet. App. 492, 495 (1992). Thus, while the veteran is competent to report what comes to her through her senses, she does not have medical expertise. See Layno v. Brown, 6 Vet. App. 465 (1994). Therefore, she cannot provide a competent opinion regarding diagnosis and causation. However, the Federal Circuit has held that lay evidence is one type of evidence that must be considered and competent lay evidence can be sufficient in and of itself. The Board, however, retains the discretion to make credibility determinations and otherwise weigh the evidence submitted, including lay evidence. See Buchanan v. Nicholson, 451 F.3d 1331, 1335 (Fed. Cir. 2006). This would include weighing the absence of contemporary medical evidence against lay statements. In Jandreau v. Nicholson, 492 F. 3d 1372 (Fed. Cir. 2007), the Federal Circuit determined that lay evidence can be competent and sufficient to establish a diagnosis of a condition when (1) a layperson is competent to identify the medical condition (noting that sometimes the layperson will be competent to identify the condition where the condition is simple, for example a broken leg, and sometimes not, for example, a form of cancer), (2) the layperson is reporting a contemporaneous medical diagnosis, or (3) lay testimony describing symptoms at the time supports a later diagnosis by a medical professional. The relevance of lay evidence is not limited to the third situation, but extends to the first two as well. Whether lay evidence is competent and sufficient in a particular case is a question of fact. Once evidence is determined to be competent, the Board must determine whether such evidence is also credible. See Layno, supra (distinguishing between competency ("a legal concept determining whether testimony may be heard and considered") and credibility ("a factual determination going to the probative value of the evidence to be made after the evidence has been admitted")). Barr v. Nicholson, 21 Vet. App. 303 (2007). When all the evidence is assembled, VA is responsible for determining whether the evidence supports the claim or is in relative equipoise, with the veteran prevailing in either event, or whether a preponderance of the evidence is against a claim, in which case, the claim is denied. Gilbert v. Derwinski, 1 Vet. App. 49 (1990). A. Sleep problems/fatigue/sleep apnea. The Veteran claims that his sleep problems are due to an undiagnosed illness, which manifested after his return from Saudi Arabia. In order for a disability to be awarded service connection under the provisions of 38 U.S.C.A. § 1117; 38 C.F.R. § 3.317(a), the disorders may not be attributable to a known diagnosis. Here, the Board notes the Veteran's complaints of sleep problems, to include loud snoring and fatigue, have been attributed to a diagnosis of obstructive sleep apnea. As this is a known clinical diagnosis, service connection is not warranted based on having an undiagnosed illness. This does not preclude consideration of the Veteran's claim on a direct causation basis. While the record shows the Veteran has been diagnosed with sleep apnea, the preponderance of the evidence is against a finding that it is related to the Veteran's active duty service period. The Veteran's service treatment records are completely silent with respect to any complaints or findings of a sleep disorder. Post service treatment records do not show any findings of obstructive sleep apnea until April 2007; moreover, there is no competent evidence that links it to service. In sum, the evidence is not in relative equipoise. The file contains no record of sleep apnea diagnosed during service. It wasn't until April 2007 that he was diagnosed with OSA; however, the record does not contain any medical evidence linking sleep apnea to service. Though the Veteran contends that he currently has sleep apnea that is related to his military service, there is no medical evidence on file supporting the Veteran's assertions and his statements do not constitute competent evidence of a medical nexus opinion. Espiritu v. Derwinski, 2 Vet. App. 492, 494-95 (1992). In the Board's judgment, the disorder in question, which was diagnosed on the basis of clinical and laboratory examinations, is not the type of disability that can be diagnosed by a layman. Jandreau, supra. Thus, while the Veteran is competent to report sleep problems and fatigue, he does not have medical expertise to diagnose the underlying disability (sleep apnea). See, e.g., Layno v. Brown, 6 Vet. App. 465 (1994). The statements from the Veteran are not competent evidence on the question of medical causation, that is, the relationship between the current sleep apnea and his military service. In this case, a layperson cannot provide a competent opinion regarding diagnosis or causation. For this reason, and because the presumption of service connection due to an undiagnosed illness is not applicable, service connection for obstructive sleep apnea is not warranted. 38 U.S.C.A. §§ 1110, 1117, 1118, 1131, 38 C.F.R. §§ 3.303, 3.317(a) (1). Thus, the preponderance of the evidence is against the claim and the appeal must therefore be denied. 38 U.S.C.A. § 5107(b); Ortiz v. Principi, 274 F.3d 1361, 1364 (Fed. Cir. 2001); Gilbert v. Derwinski, 1 Vet. App. 49, 55-57 (1990). B. Vertigo. As previously noted, the Board must determine whether the evidence supports the claim or is in relative equipoise, with the Veteran prevailing in either case, or whether the preponderance of the evidence is against the claim, in which case, service connection must be denied. Gilbert v. Derwinski, 1 Vet. App. 49 (1990). In weighing the evidence of record in the present case, the Board is of the opinion that the weight of the evidence is in equipoise as to a finding that the Veteran's benign paroxysmal vertigo is are causally related to his service-connected tinnitus. Tinnitus is "a sensation of noise (as a ringing or roaring) that is caused by a bodily condition (as wax in the ear or a perforated tympanic membrane"). Butts v. Brown, 5 Vet. App. 532, 540 (1993). Tinnitus is a noise in the ears, such as ringing, buzzing, roaring, or clicking. YT v Brown, 9 Vet. App. 195, 196 (1996). Tinnitus is a ringing, buzzing noise in the ears. Kelly v. Brown, 7 Vet. App. 471, 472 (1995). "Tinnitus can be caused by a number of conditions, including injuries, acute diseases, and drug reactions [but] disablement from tinnitus does not depend on its origin." 59 Federal Register 17297 (April 12, 1994). Moreover, tinnitus is one of the disabilities which the Court has specifically held the lay person is capable of observing. See Charles v. Principi, 16 Vet. App. 370, 374-375 (2002); Washington v. Nicholson, 19 Vet. App. 362, 368 (2005). The records show that the Veteran is currently service connected for tinnitus. And, clinical treatment records show several complaints of positional vertigo on a periodic basis and he has been given a variety of medications to treat the symptoms. Following a VA examination in April 2007, the VA examiner stated that, based upon discussion with the Veteran regarding the Vertigo, it was the opinion that it is not likely that vertigo, stated as secondary to his tinnitus, is related to military service. In light of the above statement, while the examiner stated that the Veteran's vertigo was not related to service, he also states that the Vertigo was secondary to tinnitus. In this regard, it is noteworthy that one qualified medical expert has held that the Veteran's benign paroxysmal vertigo is a probable result of his tinnitus, whether due to acoustic trauma or being exposed to toxic materials. The Board finds that this a reasonable conclusion, based upon medical expertise and a credible, hands-on neurological and Audiological assessment of the Veteran's particular circumstances and clinical findings. Moreover, the Board notes that even in the Rating Schedule and other regulatory discussions of symptoms associated with a myriad of disabilities in which dizziness or vertigo may well be an integral component, e.g., in concussion injuries, hypertension, headaches, or in tinnitus which progresses to Meniere's disease. In fact, dizziness which may be manifested as vertigo, positional or otherwise, is found as an integral component to variety of other disabilities, for several of which the Veteran already has service connection. Accordingly, it would be difficult to isolate benign positional vestibular disorder or vertigo as having a sole source in this case, and such specificity is unnecessary. Although the evidence is not unequivocal, the Board finds, without determining error in the action by the RO, that a reasonable doubt is raised which must be resolved in the Veteran's favor and that benign paroxysmal vertigo is either the result of service or cannot be dissociated from one or more of the Veteran's service-connected disability. IV. Legal analysis-Higher Evaluations. Disability evaluations are determined by evaluating the extent to which a Veteran's service-connected disability adversely affects his ability to function under the ordinary conditions of daily life, including employment, by comparing his symptomatology with the criteria set forth in the Schedule for Rating Disabilities (rating schedule). 38 U.S.C.A. § 1155 (West 2002 & Supp. 2009); 38 C.F.R. §§ 4.1, 4.2, 4.10 (2009). If two evaluations are potentially applicable, the higher evaluation will be assigned if the disability picture more nearly approximates the criteria required for that evaluation; otherwise, the lower rating will be assigned. 38 C.F.R. § 4.7 (2009). A disability may require re-evaluation in accordance with changes in a Veteran's condition. It is thus essential, in determining the level of current impairment, that the disability be considered in the context of the entire recorded history. 38 C.F.R. § 4.1. However, where an award of service connection for a disability has been granted and the assignment of an initial evaluation is at issue, separate evaluations can be assigned for separate periods of time based on the facts found. In other words, the evaluations may be "staged." Fenderson v. West, 12 Vet. App. 119, 126 (2001). When all the evidence is assembled, the Board is then responsible for determining whether the evidence supports the claim or is in relative equipoise, with the appellant prevailing in either event, or whether the preponderance of the evidence is against the claim, in which case the claim is denied. See 38 U.S.C.A. § 5107(a); 38 C.F.R. § 3.102; and Gilbert v. Derwinski, 1Vet. App. 49, 55 (1990). A. Polyarthralgia. The Veteran's service-connected polyarthralgias has been rated under the rpovisions of Diagnostic Code 5025, which addresses fibromyalgia. When the symptoms associated with fibromyalgia require constant medication for control, a 10 percent rating is for assignment. When the symptoms are episodic, with exacerbations often precipitated by environmental or emotional stress or by overexertion, but are present more than one-third of the time, a 20 percent rating is assigned. 38 C.F.R. § 4.71a, Diagnostic Code 5025. After having carefully reviewed the evidence of record, the Board finds that the preponderance of the evidence is against an initial evaluation in excess of 10 percent for polyarthralgias since September 5, 2006. While the record indicates that the Veteran has numerous areas of joint and muscle pain, his symptoms have improved with over the counter medication. Moreover, the objective clinical findings do not show episodic symptoms with exacerbations precipitated by environmental or emotional stress or by overexertion or being present more than one-third of the time; nor are they constant, or nearly so, and refractory to therapy. In view of the foregoing, the preponderance of the competent medical evidence is against a higher rating for polyarthralgias at any time since September 5, 2006. The Veteran does not meet the criteria for a higher rating under Diagnostic Code 5025. While the Veteran has alleged having exacerbations of his disability, the 10 percent evaluation contemplates such exacerbations. 3 8 C.F.R. § 4.1 (degrees of disability are considered adequate to compensate for considerable loss of working time from exacerbations or illnesses proportionate to the severity of the several grades of disability). The September 2008 VA examination occurred after the claimed instances of that his disability was exacerbated. The clinical findings do not show that the service-connected disability sustained a permanent worsening to warrant an evaluation in excess of 10 percent under Diagnostic Code 5025. See 38 C.F.R. § 4.71a, Diagnostic Code 5025. In evaluating the Veteran's service-connected polyarthralgias, the Board is cognizant of the provisions of 38 C.F.R. §§ 4.40, 4.45, and 4.59, as well as the holding in DeLuca v. Brown, 8 Vet. App. 202, 206 (1995). There is, however, no evidence of such objective signs as disuse atrophy, abnormal movement, weakness, or pain on motion against resistance which would support an increased rating under these regulations. The Board considered whether the case should be referred to the Director of the VA Compensation and Pension Service for extra-schedular consideration under 38 C.F.R. § 3.321(b) (1). The veteran has not, however, required frequent hospitalization for her service-connected disability and the manifestations of such are consistent with the assigned schedular evaluation. In sum, there is no indication that the average industrial impairment from the disability would be in excess of that contemplated by the evaluations assigned for the disability. Therefore, referral of this case for extra-schedular consideration is not in order. See Floyd v. Brown, 9 Vet. App. 88, 95 (1996); Bagwell v. Brown, 9 Vet. App. 337 (1996). In view of the denial of entitlement to an increased evaluation, the Board finds no basis upon which to predicate the assignment of "staged" ratings pursuant to Fenderson. In reaching the conclusions above the Board has considered the applicability of the benefit of the doubt doctrine. However, as the preponderance of the evidence is against the veteran's claim, that doctrine is not applicable in the instant appeal. See 38 U.S.C.A. § 5107(b); Ortiz v. Principi, 274 F.3d 1361, 1364 (Fed. Cir. 2001); Gilbert v. Derwinski, 1 Vet. App. 49 (1990). Therefore, the appeal must be denied. B. Multi-focal tremors. The Veteran lacks a definitive diagnosis that clearly places his condition in one of the diagnostic codes listed under neurological conditions and convulsive disorders. His condition, therefore, must be rated by analogy to a similar condition. See 38 C.F.R. §§ 4.20, 4.27 (2008). The RO rated his disability as analogous to a convulsive tic. 38 C.F.R. § 4.124, Diagnostic Codes (DCs) 8911, 8103. Under Diagnostic Code 8103, the rating for convulsive tic depends upon the frequency and severity of attacks and the muscle groups involved. A noncompensable rating is warranted when the disorder is mild, a 10 percent rating is warranted when the disorder is moderate, and a maximum 30 percent rating is warranted when the disorder is severe. 38 C.F.R. § 4.124a, Diagnostic Code 8103. The terms "mild," "moderate," and "severe" are not defined in the rating schedule; rather than applying a mechanical formula, VA must evaluate all the evidence to the end that its decisions are equitable and just. 38 C.F.R. § 4.6. The Veteran's disability has not been described as a severe tremor. Moreover, severe symptomatology is not otherwise shown. For example, the VA examiner in September 2008 stated that he did not feel that EMG/NCV were appropriate since the situation occurred at unknown intervals, and did not cause paralysis. No other evidence shows more than moderate symptoms. Consideration has also been given regarding whether the schedular evaluation is inadequate, thus requiring that the RO refer a claim to the Chief Benefits Director or the Director, Compensation and Pension Service, for consideration of "an extra-schedular evaluation commensurate with the average earning capacity impairment due exclusively to the service-connected disability or disabilities." 38 C.F.R. § 3.321(b) (1) (2009); Barringer v. Peake, 22 Vet. App. 242, 243-44 (2008) (noting that the issue of an extraschedular rating is a component of a claim for an increased rating and referral for consideration must be addressed either when raised by the veteran or reasonably raised by the record). An extra-schedular evaluation is for consideration where a service-connected disability presents an exceptional or unusual disability picture with marked interference with employment or frequent periods of hospitalization that render impractical the application of the regular schedular standards. Floyd v. Brown, 9 Vet. App. 88, 94 (1996). An exceptional or unusual disability picture occurs where the diagnostic criteria do not reasonably describe or contemplate the severity and symptomatology of the veteran's service- connected disability. Thun v. Peake, 22 Vet. App. 111, 115 (2008). If there is an exceptional or unusual disability picture, then the Board must consider whether the disability picture exhibits other factors such as marked interference with employment and frequent periods of hospitalization. Id. at 115-116. When those two elements are met, the appeal must be referred for consideration of the assignment of an extraschedular rating. Otherwise, the schedular evaluation is adequate, and referral is not required. 38 C.F.R. § 3.321(b)(1); Thun, 22 Vet. App. at 116. In this regard, the schedular evaluation in this case is not inadequate. The Veteran has not required frequent hospitalization due to service-connected disorders. Moreover, marked interference with employment has not been shown. In the absence of any additional factors, the RO's failure to consider or to refer this issue for consideration of an extraschedular rating was not prejudicial. C. Irritable bowel syndrome. The Veteran currently has a 10 percent rating for his IBS under 38 C.F.R. § 4.114, DC 7319. Under DC 7319, a 10 percent evaluation requires moderate irritable colon syndrome with frequent episodes of bowel disturbance with abdominal distress; and the highest available rating for this condition, 30 percent, requires severe irritable colon syndrome with diarrhea, or alternating diarrhea and constipation, with more or less constant abdominal distress. Id. With the above criteria in mind, the relevant facts will be summarized. Service connection for irritable bowel syndrome was granted by a September 2008 rating decision. A 10 percent rating was assigned. Pertinent evidence thereafter includes reports from an April 2007 VA examination that showed the Veteran reported alternating constipation and diarrhea on a daily basis. He also described periods of cramping followed by diarrhea, early satiety and flatulence. On examination, the abdomen was normal, with no palpable masses or guarding. On the occasion of another VA examination in September 2008, the Veteran reported a history of severe cramps that are relieved by bowel movements, which is mostly diarrhea. He stated that he was currently taking medications that have improved his symptoms. The cramping and diarrhea were described as very infrequent. Applying the pertinent criteria to the facts summarized above, while alternating diarrhea and constipation has been demonstrated by some of the clinical evidence, the medical record reflects intermittent but not "more or less constant," abdominal distress. Moreover, as noted above, during the most recent VA examination, the Veteran reported improved symptoms with infrequent diarrhea and cramping. There is otherwise no objective evidence indicating that the Veteran has more or less "constant" abdominal stress associated with his irritable bowel syndrome. As such, an increased rating of 30 percent rating for irritable bowel syndrome under DC 7319 may not be assigned. In exceptional cases where schedular evaluations are found to be inadequate, the RO may refer a claim to the Chief Benefits Director or the Director, Compensation and Pension Service, for consideration of "an extra-schedular evaluation commensurate with the average earning capacity impairment due exclusively to the service-connected disability or disabilities." 38 C.F.R. § 3.321(b) (1) (2009). The governing norm in these exceptional cases is: A finding that the case presents such an exceptional or unusual disability picture with such related factors as marked interference with employment or frequent periods of hospitalization as to render impractical the application of the regular schedular standards." Floyd v. Brown, 9 Vet. App. 88, 94 (1996). In this case, however, the schedular evaluation is not inadequate. Ratings in excess of that currently assigned are provided for certain manifestations of the veteran's service- connected residuals, but those manifestations are not present in this case. Moreover, the Board finds no evidence of an exceptional disability picture. The Veteran has not required frequent hospitalizations due to his irritable bowel syndrome, and his service-connected residuals have not shown functional limitation beyond that contemplated by the 10 percent currently assigned. Accordingly, referral of this decision for extraschedular consideration is not indicated. The Veteran asserts a much more debilitating condition due to his irritable bowel syndrome than was demonstrated by the evidence cited above, and the Board fully respects the Veteran's sincere assertions in this case. However, it finds the probative weight of this positive evidence to be overcome by the more objective negative evidence cited above. See Routen v. Brown, 10 Vet. App. 183, 186 (1997), aff'd sub nom. Routen v. West, 142 F.3d 1434 (Fed. Cir. 1998), cert. denied, 119 S. Ct. 404 (1998). See also Espiritu v. Derwinski, 2 Vet. App. 492 (1992); Francisco v. Brown, 7 Vet. App. at 55 (1994). Thus, as the probative weight of the negative evidence exceeds that of the positive, the claim must be denied. Gilbert v. Derwinski, 1 Vet. App. 49, 53 (1990). D. Bilateral hearing loss prior to September 19, 2008. Evaluations of bilateral hearing loss range from noncompensable to 100 percent based on organic impairment of hearing acuity, as measured by a controlled speech discrimination test (Maryland CNC) and the average hearing threshold, as measured by puretone audiometric tests at the frequencies of 1,000, 2,000, 3,000 and 4,000 Hertz. The Rating Schedule establishes 11 auditory acuity levels designated from Level I, for essentially normal hearing acuity, through level XI, for profound deafness. Under 38 C.F.R. § 4.85, Table VI (Numeric Designation of Hearing Impairment Based on Puretone Threshold Average and Speech Discrimination) is used to determine a Roman numeral designation (I through XI) for hearing impairment based on a combination of the percent of speech discrimination (horizontal rows) and the puretone threshold average (vertical columns). The Roman numeral designation is located at the point where the percentage of speech discrimination and puretone average intersect. 38 C.F.R. § 4.85(b). The puretone threshold average is the sum of the puretone thresholds at 1,000, 2,000, 3,000 and 4,000 Hertz, divided by 4. This average is used in all cases to determine the Roman numeral designation for hearing impairment. 38 C.F.R. § 4.85(d). Under 38 C.F.R. § 4.85, Table VII (Percentage Evaluations for Hearing Impairment), the percentage evaluation is determined by combining the Roman numeral designations for hearing impairment of each ear. The horizontal rows represent the ear having the better hearing and the vertical columns the ear having the poor hearing. The percentage evaluation is located at the point where the rows and column intersect. 38 C.F.R. § 4.85(e). 38 C.F.R. § 4.86(a) specifies that when the puretone threshold at each of the four specified frequencies (1000, 2000, 3000, and 4000 Hertz) is 55 decibels or more, the rating specialist will determine the Roman numeral designation for hearing impairment from either Table VI or Table VIA, whichever results in the higher numeral. Each ear will be evaluated separately. 38 C.F.R. § 4.86(a). In essence, defective hearing is rated on the basis of a mere mechanical application of the rating criteria. Lendenmann v. Principi, 3 Vet. App. 345, 349 (1992). When the puretone threshold at each of the four specified frequencies (1,000, 2,000, 3,000, and 4,000 Hertz) is 55 decibels or more, Table VI or Table VIa is to be used, whichever results in the higher numeral. 38 C.F.R. § 4.86(a). Additionally, when the puretone threshold is 30 decibels or less at 1,000 Hertz, and 70 decibels or more at 2,000 Hertz, Table VI or Table VIa is to be used, whichever results in the higher numeral. Thereafter, that numeral will be elevated to the next higher numeral. 38 C.F.R. § 4.86(b). The evidence of record herein indicates that the Veteran's bilateral hearing loss pattern does not fit the requirements of an unusual pattern of hearing impairment for the period prior to September 19, 2008. After a review of the evidence, the Board finds that the criteria for a compensable rating for the veteran's service- connected bilateral hearing loss disability are not met for the period prior to September 19, 2008. Accordingly, his claim for a compensable rating fails for the period prior September 19, 2008. Based on the April 2007 VA examination report, audiological evaluation shows a right ear puretone decibel loss of 35 with speech recognition of 88 percent. This corresponds to a numeric designation of Level II hearing in the right ear. 38 C.F.R. § 4.87, Table VI (2009). He has a left ear average puretone decibel loss of 46.25 with speech recognition of 92 percent. These findings are consistent with Level I hearing in the left ear. These combined numeric designations result in a rating of 0 percent under Diagnostic Code 6100. 38 C.F.R. § 4.85, Table VII (2009). No other medical records contain the puretone threshold average and speech discrimination percentage scores needed to determine the level of hearing loss according to VA regulation prior to September 19, 2008. Accordingly, the Board finds that the preponderance of the evidence is against entitlement to a compensable disability rating for bilateral hearing prior to September 19, 2008. 38 C.F.R. §§ 4.3, 4.85, DC 6100. E. Bilateral Hearing Loss Since September 19, 2008. The Veteran underwent a VA Audiological evaluation on September 19, 2008. The average puretone threshold was 65 dB in the right ear and 72.5 dB in the left ear. Speech audiometry revealed speech recognition ability of 72 percent in the right ear and 80 percent in the left ear. Applying the results from the September 2008 VA audioligcal evaluation yields a Roman numeral value of V for the right ear and IV for the left ear. Applying these values to Table VII, the Board finds that the Veteran's bilateral hearing loss would be evaluated as 10 percent disabling. However, since each of the puretone thresholds is 55 decibels or more, the Board must determine the Roman numeral designation using Table VIA, and then use the higher numeral in rating his hearing loss. Using this table, the Veteran's bilateral hearing loss meets the criteria for a 20 percent rating. The findings from the September 2008 Audiological evaluation report yield a numerical designation of V for the right ear - between 63 and 69 percent average puretone decibel hearing loss - and a numerical designation of VI for the left ear - between 70 and 76 percent average puretone decibel hearing loss. Entering the category designations for each ear into Table VII produces a disability percentage rating of 20 percent. Thus, a 20 percent rating is warranted for the veteran's bilateral hearing loss. The Board has considered lay statements provided by the veteran to determine whether a disability rating higher than 20 percent is appropriate. However, his contentions are insufficient to establish entitlement to a disability rating higher than 20 percent for defective hearing because ". . . disability ratings for hearing impairment are derived by a mechanical application of the rating schedule to the numeric designations assigned after audiometric evaluations are rendered." Lendenmann, 3 Vet. App. at 349. Here, the mechanical application clearly establishes a 20 percent rating for the Veteran's bilateral hearing loss disability from September 19, 2008. For the reasons and bases, the Board finds that the evidence supports a 20 percent rating for the Veteran's service- connected bilateral hearing loss, but that the preponderance of the evidence is against a disability rating higher than 20 percent. The appeal is granted to this extent only. Further, although it is possible to assign an extra-schedular evaluation, the Board finds no reason to refer the case to the Compensation and Pension Service to consider whether it is warranted. In this case, there is no evidence of any hospitalization associated with the disability in question. In addition, the Board finds no evidence that the Veteran's disability markedly interferes with his ability to `work above and beyond that contemplated by his separate schedular ratings. See 38 C.F.R. § 4.1 (indicating that generally, the degrees of disability specified in the Rating Schedule are considered adequate to compensate for considerable loss of working time from exacerbations or illnesses proportionate to the severity of the several grades of disability). ORDER Service connection for a sleep disorder, fatigue, and sleep apnea, diagnosed as obstructive sleep apnea, is denied. Service connection for vertigo is granted. Entitlement to a rating in excess of 10 percent for polyarthralgias is denied. Entitlement to a rating in excess of 10 percent for multi- focal tremors is denied. Entitlement to a rating in excess of 10 percent for irritable bowel syndrome is denied. Entitlement to an initial compensable rating for bilateral hearing loss prior to September 19, 2008 is denied. A 20 percent rating is granted for bilateral hearing loss from September 19, 2008, subject to the laws and regulations governing the payment VA compensation. REMAND The law provides that VA shall make reasonable efforts to notify a claimant of the evidence necessary to substantiate a claim and requires VA to assist a claimant in obtaining that evidence. 38 U.S.C.A. §§ 5103, 5103A (West 2002); 38 C.F.R. § 3.159 (2009). Such assistance includes providing the claimant a medical examination or obtaining a medical opinion when such an examination or opinion is necessary to make a decision on a claim. 38 U.S.C.A. §§ 5103, 5103A (West 2002); 38 C.F.R. § 3.159 (2009). A. S/C respiratory disorder, including asthma. Concerning the Veteran's claim for a respiratory disorder, claimed as asthma, he maintains that he developed problems due to exposure to oil field fires and breathing in smoke from the oil fields. The Veteran indicated that, while in the gulf, he had a constant cough because he was just breathing the oil field smoke and he would have associated wheezing. The service treatment records show that at discharge, in July 1993, the Veteran reported occasional pleuritic chest pain at rest; however, clinical evaluation of the chest and lungs were normal, and a chest x-ray was normal. Following separation from active service, VA and private medical records include clinical findings of asthma diagnosed in May 2005. During a VA gulf war examination in April 2007, it was noted that the Veteran had a respiratory condition by history, but he had normal chest x-ray and pulmonary function test was normal. It was noted that his claim was not supported by any objective medical evidence to substantiate chronic illness. However, on the occasion of a subsequent VA examination, in September 2008, the Veteran was diagnosed with asthma, associated with coughing and breathing difficulty. Although the examiner diagnosed asthma, the examiner did not express whether it was at least as likely as not that any respiratory disorder, including asthma, was causally related to active service. Because of the in-service and post- service complaints and treatment documented in the record, the Board finds that another examination is required in order to address the etiology of the Veteran's respiratory disorder. See McClendon v. Nicholson, 20 Vet. App. 79 (2006). B. S/C for an acquired psychiatric disorder, including PTSD and depression. The Veteran indicated that he developed PTSD as a result of incidents which occurred while on active duty in the Persian Gulf. The Veteran indicates that he was assigned to the HHC 4th Brigade, 1st Armor Division and his unit was stationed near Khamisiyah, Iraq. The Veteran stated that in early March 1991, rockets were destroyed in the pit near Khamisiyah, and nerve agents were released into the air. The Veteran recalled almost being killed when his platoon sergeant placed him outside the perimeter to perform guard duty; he was almost the subject of friendly fire because he was put in the wrong area (on the enemy side). He also recalled picking up body parts from dead Iraqi solders and seeing others burned alive inside their vehicles. The Veteran indicates that, as a result of his experiences in Iraq, he suffers from depression, panic attacks, irritability, anger outbursts, anxiety and mood changes. Verification of the purported stressor event is warranted. The claims folder contains competent evidence reflecting that the Veteran has a psychological disorder variously characterized as PTSD and depression. During a clinical visit in April 2006, the Veteran indicated that he was not sleeping well; he was dreaming about the war. The assessment was PTSD. The record also indicates that the Veteran's psychological disabilities may be associated with active service. The service treatment records indicate that at his separation examination in October 1989, he was seen for a mental evaluation. He was diagnosed with mild depression. He was also diagnosed with occupational stress. Thus, it is conceivable that the Veteran's psychological disabilities were manifested during service. In view of this, the Veteran should be afforded a VA examination to identify his current, correct psychiatric diagnosis (es) and to specifically address whether any are related to service as detailed below. 38 C.F.R. § 3.159(c) (4) (2009). C. Increased rating for residuals, surgery, left great toe. The Veteran maintains that his left foot disorder is more disabling that reflected by the 20 percent rating currently assigned. The Veteran maintains that his disability has worsened since his last examination. The service representative notes that the most recent VA examination for the left great toe was performed over 5 years ago, and his disability has definitely worsened over the years. The Veteran reports pain and swelling. Whether an examination is sufficiently contemporaneous to properly rate the current severity of the veteran's disability depends on the particular circumstances of the individual case. Snuffer v. Gober, 10 Vet. App. 400 (1997). Therefore, the Veteran should undergo additional VA examinations of his left great toe in order to accurately assess the severity, symptomatology, and manifestations of his disability. 38 U.S.C.A. § 5103A (d) (1); 38 C.F.R. § 3.159(c) (4). The Veteran must be advised of the importance of reporting to the scheduled examinations and of the possible adverse consequences, to include the denial of his claims, of failing to so report. See 38 C.F.R. § 3.655 (2009). In light of the discussion above, and to ensure full compliance with due process requirements, the case is hereby REMANDED to the RO via the Appeals Management Center (AMC), in Washington, D.C., for the following actions: 1. The RO should obtain the names and addresses of all medical care providers, VA as well as non-VA, who have treated the Veteran for his respiratory and psychiatric disorders since his separation from service. After securing the necessary releases, the RO should obtain these records. If the records are not available, a notation to that effect should be placed in the claims file and the Veteran notified of the problem. 2. Review the file in detail and prepare a summary of the Veteran's claimed stressors, including those discussed in the body of this remand. The summary and all associated documents should be sent to U.S. Army and Joint Services Records Research Center (JSRRC), Kingman Building, Room 2C08, 7701 Telegraph Road Alexandria, VA 22315-3802. JSRRC should be requested to provide any information that might corroborate the veteran's alleged in- service stressor. 3. The Veteran should also be afforded a VA psychiatric examination to determine the nature and likely etiology of any currently diagnosed psychiatric disorder. The claims folder should be made available to the examiner for review and all indicated testing should be conducted. Based on the examination and review of the record, the examiner should identify all psychiatric impairment that is present and describe the nature of any that has been identified. As to any psychiatric disorder diagnosed, the examiner should offer an opinion as to whether it is at least as likely as not that the condition is related to the Veteran's service. If the examiner concludes that the veteran has PTSD, the examiner should further identify the stressor(s) considered to have caused the disorder. The opinion should adequately summarize the relevant history and clinical findings, and provide explanations as to all medical conclusions rendered. 4. Schedule the Veteran for an appropriate VA examination to determine the nature and etiology of any current respiratory disability, claimed as asthma. The claims folder and a copy of this REMAND must be made available to and reviewed by the examiner in conjunction with the examination. All necessary diagnostic tests, if any, should be completed. Following completion of the examination, the examiner should specifically comment as to whether the veteran currently has asthma. Should it be determined that the Veteran does, in fact, have asthma, the examiner should provide an opinion as to whether it is at least as likely as not (a 50 percent probability or more) that it had its origin during active military service. The examiner should provide a complete rationale for any opinion provided. 5. The veteran should be scheduled for a VA examination to determine the current degree of left foot impairment. The veteran's file must be made available for review by the examiner. a.) The examiner should comment whether the right foot disability is moderate, moderately severe or severe. The examination should include a description of range of motion evaluations. b.) The examiner is asked to describe any additional functional loss due to pain (supported by adequate pathology and evidenced by the visible behavior of the claimant undertaking the motion) as well as weakness, excess fatigability, incoordination or pain on movement. Any additional functional loss should be expressed in terms of additional limitation of motion. c.) The examiner is asked to describe any additional functional loss during flare- ups or exacerbations. The additional functional loss should be expressed in terms of additional limitation of motion. If flare-ups or exacerbations can not be duplicated on examination, the examiner is asked to make a reasonable estimate. 6. To help avoid future remand, the RO must ensure that all requested actions have been accomplished (to the extent possible) in compliance with this REMAND. If any action is not undertaken, or is taken in a deficient manner, appropriate corrective action should be undertaken. See Stegall v. West, 11 Vet. App. 268 (1998). 7. Thereafter, the RO should readjudicate the Veteran's claims on the basis of all evidence of record and all applicable laws and regulations. If the benefits sought on appeal remain denied, the Veteran and his representative should be provided a supplemental statement of the case (SSOC), which includes a summary of additional evidence submitted, and any additional applicable laws and regulations. The SSOC must provide reasons and bases for the decision reached. Thereafter, the Veteran and his representative should be given the opportunity to respond. After the above actions have been accomplished, the case should be returned to the Board for further appellate consideration, if otherwise in order. By this REMAND the Board intimates no opinion, either legal or factual, as to the ultimate determination warranted in this case. The purposes of this REMAND are to further develop the record and to accord the Veteran due process of law. The appellant has the right to submit additional evidence and argument on the matter or matters the Board has remanded. Kutscherousky v. West, 12 Vet. App. 369 (1999). This claim must be afforded expeditious treatment. The law requires that all claims that are remanded by the Board of Veterans' Appeals or by the United States Court of Appeals for Veterans Claims for additional development or other appropriate action must be handled in an expeditious manner. See 38 U.S.C.A. §§ 5109B, 7112 (West Supp. 2009). ______________________________________________ L. M. BARNARD Acting Veterans Law Judge, Board of Veterans' Appeals Department of Veterans Affairs
