G90: Disorders of autonomic nervous system
G90.5: Complex regional pain syndrome type I
Complex regional pain syndrome type I (CRPS I), also known as reflex sympathetic dystrophy (RSD), is a chronic condition that typically affects an arm or a leg, and develops after an injury, surgery, stroke, or heart attack. It is characterized by severe, prolonged pain that is considered out of proportion to the severity of the initial injury. The exact cause of CRPS I is unknown, but it is thought to involve abnormal inflammation and changes in the nerves in the affected area. Symptoms include prolonged or excessive pain, changes in skin color, temperature and texture, swelling and sensitivity in the affected area, and limited mobility. The symptoms may change over time and vary from person to person. Early diagnosis and appropriate management are important as the condition can become disabling if not treated promptly.
