Causes of peripheral neuropathy: Diabetes and beyond.

CASE 1 u Sally G, age 46, has been experiencing paresthesias for the past 3 months. She says that when she is cycling, the air on her legs feels much cooler than normal, with a similar feeling in her hands. Whenever her hands or legs are in cool water, she says it feels as if she’s dipped them into an ice bucket. Summer heat makes her skin feel as if it's on fire, and she’s noticed increased sweating on her lower legs. She complains of itching (although she has no rash) and she’s had intermittent tingling and burning in her toes. On neurologic exam, she demonstrates normal strength, sensation, reflexes, coordination, and cranial nerve function.
