Inflammation of the posterior tibial nerve, which may cause pain or numbness in the heel and sole.
Medical records that document the degree of motor and sensory loss in your foot are central to this rating. Nerve conduction studies or electromyography can show the extent of posterior tibial nerve damage. Physical examination findings are especially important: records showing whether you can flex your toes, how strong adduction is, and how much plantar flexion you retain help VA place your condition at the complete or a specific incomplete level. Reports of painful, burning (causalgic) sensations in the sole of the foot support the higher end of the scale. If your symptoms are purely sensory with no motor involvement, the regulation limits the rating to mild or, at most, moderate. Statements from you or people who know you describing how foot pain or weakness affects standing, walking, or your ability to work can help show functional impact at each level.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
