Additional treatment options

Neuropathy self-management

Patient education and self-management strategies including foot care, activity modification, protective footwear, and avoidance of nerve insults to prevent progression.

lifestyle

Nerve conduction study follow-up

Periodic neurophysiological testing to monitor nerve conduction velocity changes, assess treatment response, and guide decisions about escalating or modifying therapy.

monitoring

B-vitamin supplementation

Nutritional supplementation with B-complex vitamins that support nerve health and function, potentially improving nerve conduction parameters in certain deficiency states.
