Complex regional pain syndrome (CRPS) is a chronic pain condition most often affecting one of the limbs (arms, legs, hands, or feet), usually after an injury or trauma to that limb. CRPS is believed to be caused by damage to, or malfunction of, the peripheral and central nervous systems.
Symptoms of CRPS include:
• Dramatic changes in skin temperature, color, or texture
• Intense burning pain
• Extreme skin sensitivity
• Swelling and stiffness in affected joints
• Decreased ability to move the affected body part
The symptoms are usually much worse than you would expect after the injury. CRPS pain continues after the original injury has healed. The symptoms are often severe and have a big effect on day-to-day activities. The pain may spread to other limbs. The pain is long-lasting, and gets worse rather than better with time. Staying in bed and not moving around may make the pain and stiffness worse.
