The Board has granted service connection for multiple joint pain and degenerative joint disease of both knees, finding that the veteran's current conditions are related to his military service. The decision is based on new evidence provided by the veteran.

The Board finds that additional medical opinions are needed to determine if the Veteran's joint pain, gastrointestinal disorder, fatigue, and headaches are due to undiagnosed illness or medically unexplained chronic multisymptom illnesses.,The Board finds that additional medical opinions are needed to determine if the Veteran's ulcerative colitis is related to in-service exposure to environmental hazards or otherwise related to service.,The Board finds that additional medical opinions are needed to determine if the Veteran's fatigue is due to undiagnosed illness or medically unexplained chronic multisymptom illnesses.,The Board finds that an examination is needed to determine if the Veteran's headaches are related to in-service TBI or otherwise related to service.,The Board finds that an examination is needed to determine if the Veteran's right hand wrist strain and left hand wrist strain are related to service.,The Board finds that an examination is needed to determine if the Veteran's disability of the left hand fingers and disability of the right hand fingers are related to service.,The Board finds that an examination is needed to determine if the Veteran's cervical spine disability is related to service.,The RO combined the rating for residuals of concussion with PTSD. The Board finds that a separate rating for residuals of concussion should be considered in light of the Veteran's reported overuse injury and repetitive motion stemming from his service duties.

The Veteran's service-connected disabilities, including PTSD and depressive disorder, sciatic radiculopathy of the right and left lower extremities, intervertebral disc syndrome (claimed as low back condition), scars, degenerative joint disease of both knees, degenerative arthritis of the right shoulder, hypertension, tinnitus, bilateral nasal pinquecula with dry eyes, hernia, ear pain, and erectile dysfunction, have rendered him unable to secure or follow a substantially gainful occupation. The Board finds that his service-connected disabilities alone are at least in equipoise as to whether he is unable to obtain or maintain such employment.

The Veteran's PTSD is currently rated at 30 percent, with no specific service connection granted for other conditions. The rating reflects the current level of impairment due to PTSD alone.

The Veteran's medical conditions do not meet the criteria for special monthly pension based on need for regular aid and attendance of another person or being housebound.
