Peripheral neuropathy is a condition of the nervous system with many possible causes, which is part of what makes it so frustrating. It often shows up as burning, numbness, tingling, or electric-shock sensations in the hands and feet, along with cramping, balance problems, sensitivity, and sleep that suffers as symptoms get worse at night. Care begins with understanding what is driving the nerve irritation, then focuses on reducing symptoms and supporting nerve health so you can walk, sleep, and move more comfortably.
