Inflammation of the radial nerve, which may cause pain, weakness, or numbness in the wrist and fingers.
To support a higher rating, medical records and examination findings should reflect how much function you have lost in the affected arm. For severe incomplete paralysis, records would show significant weakness or impaired ability to extend your hand at the wrist, extend your fingers or thumb, rotate your palm upward, or grip objects, falling short of complete paralysis. For moderate or mild levels, findings would show lesser degrees of those same deficits. Nerve conduction studies and electromyography can provide objective evidence of the extent of nerve damage. If your symptoms are purely sensory, such as numbness, tingling, or pain without motor loss, the regulation directs that the rating be no higher than moderate. Statements from you or people who know you describing how weakness or sensory changes affect your ability to work, carry objects, type, or perform daily tasks help show the functional impact of your symptoms.
