The veteran's claim for service connection for a shrapnel wound of the back is granted as there is competent evidence of current disability, in-service injury consistent with combat, and an etiological relationship between the scar and the claimed shrapnel wound.

The Board denied the Veteran's petitions to reopen his previously denied claims for service connection for various conditions, including shrapnel wounds of the left leg and back, liver condition, bilateral hearing loss, peripheral neuropathy of the lower extremities, adrenal gland cyst, and thyroid disease. The evidence did not meet the criteria for reopening any of these claims.

The Board denied service connection for a shrapnel wound of the back and an increased rating for left shoulder degenerative changes. The Veteran's claims were not granted as there was no evidence to support separate service connection for the back injury, and his current disability ratings are appropriate based on the severity of his left shoulder condition.

The Board has determined that new and material evidence has not been received to reopen the claim of service connection for PTSD. The Veteran's representative filed a claim for service connection for scars from bullet wounds of the left calf, shrapnel wounds of the right ear, and back. However, there is no medical or credible lay evidence linking these conditions to 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.
