Complex regional pain syndrome (CRPS), also sometimes called reflex sympathetic dystrophy (RSD) or causalgia, is a chronic, progressive nerve disorder. Patients who have CRPS experience severe pain and other symptoms (e.g., changes in skin temperature, color, or sensitivity, swelling), often with no known cause. In some cases, the disorder develops following an injury. RSD/CRPS usually affects the arms, legs, hands, and feet, but it can occur in any part of the body.

CRPS can be difficult to diagnose and the course of the disorder often is unpredictable. Symptoms of reflex sympathetic dystrophy/complex regional pain syndrome may worsen over time and can be disabling.

It is important for patients with RSD/CRPS to work with their health care team to develop an effective treatment plan. Here are some questions to ask your doctor (e.g., neurologist, pain management specialist) about RSD/CRPS. Print this page, check off the questions you would like answered, and take it with you to your doctor appointment. The more knowledge you have about RSD/CRPS, the easier it is to make important decisions that can help reduce your pain and other symptoms.
