The Veteran is seeking compensation under 38 U.S.C.A. § 1151 for bilateral leg and knee disability as a result of VA surgical treatment on February 8, 2006. The Board has determined that additional development is needed to determine the nature and etiology of any current lower extremity disabilities.

The Board has remanded the Veteran's claims for service connection due to potential Agent Orange exposure, and a TERA-specific examination is required. The examiner must consider total potential exposure through all applicable military deployments and the synergistic, combined effect of all toxic risk activities.

The Veteran's bilateral hearing loss is not service-connected due to lack of in-service onset or continuity of symptomatology.,Service connection for a disability of the upper extremities, to include thoracic neuropathy, is denied as there is no current diagnosis and no evidence linking it to service.,Service connection for a bilateral ankle and feet disability is remanded as the VA examiner found a negative nexus to service.,Service connection for a bilateral leg and knee disability is remanded as the VA examiner found a negative nexus to service.,Service connection for a lumbar disorder, claimed as lumbar radiculopathy, is remanded as the VA examiner found a negative nexus to service.

The Board has denied the veteran's claims for service connection for a bilateral leg and knee disability and depression, finding that these conditions did not begin during or as a result of his military service.

The Board denied the veteran's claims for increased ratings for his service-connected lumbar myositis, psychoneurosis and conversion hysteria, residuals of shrapnel wounds of the left thigh and pelvis with retained foreign bodies and scars, and residuals of shell fragment wounds of the right thigh and left leg. The veteran was also denied entitlement to a total disability rating based on individual unemployability due to service-connected disabilities.
