Entitlement to service connection for a left calf condition is remanded.

Board reasoning

The Board remands for VA examinations to determine if the left calf cramps and pain are the same or different symptoms and whether they affect the same function as the left leg radiculopathy, and (if applicable) whether the left knee condition is caused or aggravated by the left calf cramping or its treatment. It emphasizes the need for medical opinion to resolve potential separate disability and interrelation, citing the need to distinguish symptomatology and functional impact and to obtain etiological and aggravation opinions with proper rationale.
