One year after bilateral lumbar sympathectomy for Raynaud's syndrome, a young woman underwent fascicular biopsy of the sural nerve to help elucidate the cause of lower limb pain. The morphological features, density, and diameter spectrum of unmyelinated fibers were normal. The sympathetic nervous system appears to contribute few, if any, axons to the total population of unmyelinated axons in this cutaneous nerve.
