Complex regional pain syndrome (CRPS) type I is an intractable pain syndrome accompanied with autonomic nerve symptoms, but without certain evidence of nerve injury. It is mainly caused by trauma, such as, fracture, sprain, contusion, etc., and is characterized by, pain (either by contact or spontaneously), allodynia, hyperalgia, vasomotor, and autonomic changes (including variable skin color changes), temperature change, swelling, edema, sweating, trophic change, and motor disturbance. We report the case of a 60-year-old woman who had suffered from severe pain on the right chest for several years. She was satisfactorily treated by pharmacologic therapy and continuous epidural nerve block.
