Nerve pain affecting the middle spine nerve roots, which may cause sharp or burning pain in the forearm and hand.
Because the ratings turn on how much nerve function you have lost, medical records and examination findings that document the degree of that loss are most useful. For complete or severe incomplete paralysis, records showing that arm movement — including raising, rotating, or pulling the arm, bending the elbow, or extending the wrist — is lost or severely limited would support a higher rating. Nerve conduction studies or electromyography results that show the extent of nerve damage can help establish severity. For moderate or mild levels, records of reduced range of motion, measurable muscle weakness, or sensory deficits in the arm are relevant. Because neuralgia is a sensory condition, your examiner's finding that involvement is wholly sensory is significant, since the regulation limits wholly sensory conditions to the mild or moderate degree. Statements from you or people who know you describing how pain or numbness affects the use of your arm in daily activities or work can help show functional impact at any 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.
