The Board has remanded the case due to insufficient evidence regarding the etiology of the veteran's bilateral lower extremity peripheral neuropathy, specifically whether it is related to his presumed exposure to herbicide agents during service.

The Veteran's claim for service connection for peripheral neuropathy of the bilateral upper and lower extremities is granted, with his exposure to herbicide agents in Vietnam considered. The Board finds that there is at least equipoise evidence supporting a nexus between the Veteran’s currently diagnosed peripheral neuropathy and his in-service contact with Agent Orange.

The Board denied service connection for various conditions, including blurred vision, peripheral neuropathy of the upper and lower extremities, poor circulation in the legs, non-alcoholic fatty liver disease, and fecal leakage, all claimed as secondary to diabetes. The Veteran's claims for increased ratings were also denied.

The claim of entitlement to service connection for a right-hand nerve injury is denied.,The claim of entitlement to service connection for a heart disorder is remanded.,The claims of entitlement to service connection for diabetes mellitus, peripheral neuropathy of bilateral upper extremities, and peripheral neuropathy of bilateral lower extremities are remanded.,The claim of entitlement to service connection for fibromyalgia is remanded.,The claims of entitlement to service connection for a left shoulder disorder and for a right shoulder disorder are remanded.

The Board has remanded the case due to insufficient medical opinions regarding whether the Veteran's peripheral neuropathy is linked to his presumed herbicide exposure from service at the Korean DMZ.
