  "abstract": "Background and Aims Adolescent complex regional pain syndrome (CRPS) is rare and there have not been conclusive treatments.Methods Case report: An 18-aged female patient had visited our pain clinic with left arm pain. In past history, ulnar nerve decompression surgery had been operated on her left elbow twice in orthopaedic clinic. After surgery, she had great pain, swelling, tremor, color changes in her left arm and hand. In physical examination, pain was over 7/10 in visual analogue scale. Allodynia and hyperalgesia existed in left hand and arm. Hot sensation was in left hand. Sweating had increased in left hand and arm. Tremor was in left hand. In three phase bone scan, blood pool and bone uptake in left hand. In bone densitometry, lumbar spine and trochanter were normal, but in upper arm, right arm was 0.806 g/cm2, left arm was 0.642 g/cm2. In magnetic resonance image of left hand, there were diffuse signal change in muscle of left hand combined with subcutaneous edema. In thermography, there were temperature differences in left hand of maximum 1.2 degrees. There were no abnormal findings in left arm x-rays. After admission, epidural catheter was inserted in left upper thoracic segment but left arm pain was not improved. The patient had left arm allodynia, hyperalgesia, severe pain, muscle weaknesses, and tremor, but there was no dramatic pain subside and functional improvements. We had planned for passive physical exercises under sedation and brachial plexus block.Results One month after last treatment, patient visited our outpatient clinic. There was much improvement in allodynia, hyperalgesia, and pain. And range of motion in wrist, elbow, were much improved.Conclusions Severe allodynia, hyperalgesia have been great problems in rehabilitation of CRPS patients. Sedation and regional nerve block would be good treatment option in CRPS patients.",
