Complex regional pain syndrome: A case report and review of the literature.

Background: Complex regional pain syndrome (CRPS) is a rare neuropathic pain disorder associated with severe pain, muscle weakness, limb edema and hyperhidrosis. Predisposing factors include fracture, surgery, stroke and spinal cord injury. CRPS may recur in the same limb or spread to other limbs to complicate management. Case Report: A 20-year old female with CRPS Type-I had sequential spread to all four limbs despite different treatment modalities, including medical therapy, nerve block, radiofrequency ablation and surgical sympathectomy. We discuss the therapeutic challenges and reviewed recent literature on current treatment options for CRPS Type-I. Conclusion: A multidisciplinary approach is needed for effective management of CRPS, and refractory disease may respond to intrathecal baclofen with morphine.
