Inflammation of the lower arm nerve roots, which may cause pain, weakness, or numbness in the hand and fingers.
Medical records documenting your diagnosis of lower nerve root neuritis and the degree of motor or sensory loss help establish which rating level applies. Nerve conduction studies, electromyography (EMG) results, and physical examination findings showing the extent of weakness, loss of grip, or impaired wrist and finger movement are directly relevant to separating mild, moderate, and severe levels.
If your involvement is wholly sensory — meaning pain, numbness, or tingling without significant motor loss — the regulation limits the rating to mild or at most moderate, so records clearly describing whether motor function is affected matter greatly.
Statements from you or people who know you describing how hand weakness or loss of function affects your ability to work, carry objects, or perform daily tasks can help show the practical impact of your symptoms. Treatment records, including notes from neurologists or orthopedic specialists, and any history of surgical or non-surgical treatment for the condition also reflect severity over time.
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.
