Nerve pain affecting all spine nerve roots, which may cause widespread sharp or burning pain in the arm and hand.
Because the rating turns on the degree of lost or impaired function, medical records that document the nature and extent of your nerve pain matter most. Exam findings that describe how much sensation or function is affected — and whether the involvement is purely sensory — help establish where your condition falls. Imaging, nerve conduction studies, or other objective tests that show the source and extent of the nerve involvement can support the record. Because the regulation distinguishes mild from moderate impairment based on how substantially function is reduced compared to complete paralysis, statements from you or people who know you that describe how the pain limits daily tasks, work, and movement can help show the degree of impairment. Records showing whether one or both sides are affected are also relevant, since the rating formula differs for the major and minor sides.
