Chronic regional pain syndrome, type 1 (CRPS1) is a complex neurologic disease characterized by chronic, severe, burning pain; hyperesthesia; soft tissue swelling; dystrophy; hyperhidrosis; vasomotor and sudomotor instability; joint stiffness; and patchy osteoporosis. Five to six million people in the United States alone suffer from CRPS1. To date, CRPS1 is poorly understood and often is not recognized clinically. This syndrome requires early detection, pain control, and treatment in tandem with physical therapy to the affected area. Part I (published in September) discussed background information on CRPS1 and sympathetic nerve blocks. Part II focuses on the remaining treatment modalities (e.g., sympathectomy, physical therapy, stimulators, trigger point injections, acupuncture, tourniquet effects, placebo effects, amputation).
