Introduction

Complex regional pain syndrome (CRPS) is an uncommon, chronic condition that usually affects your arm or leg. Rarely, the disease can affect other parts of your body. You may experience intense burning or aching pain along with swelling, skin discoloration, altered temperature, abnormal sweating and hypersensitivity in the affected area.

The nature of complex regional pain syndrome is puzzling, and the cause isn't clearly understood.

Women are more likely to be affected by complex regional pain syndrome than men are. Although complex regional pain syndrome is most common in people between the ages of 40 and 60, it can occur at any age. Treatment for complex regional pain syndrome is most effective when started early in the course of the syndrome.
