We report the case of a patient who developed complex regional pain syndrome type I, after operation for tongue cancer. A 62-year-old male underwent excision for tongue cancer, followed by reconstruction, using a left free forearm flap. Nine re-operations were required after the primary operation. Two months after the first operation, the patient complained of pain and swelling in his left hand, which spread from his left hand to the upper part of the arm and also to the right side. The range of motion of both shoulders was limited. An x-ray of the hands showed bone atrophy, thermography showed coldness, and the hand grip was weak. Based on the findings, the patient was diagnosed as having complex regional pain syndrome type I. He was started on medication and rehabilitation. The symptoms have improved slowly, and at present, 3 years after the diagnosis, most of the symptoms have disappeared, except for the left hand being numb, and the patient is able to lead an ordinary life.
