Most of the chronic pain in Machado-Joseph disease has been reported to be of musculoskeletal origin but now there seems to be different chronic pain in patients with Machado-Joseph disease. Case presentation A 29-year-old man Han Chinese Hoklo with Machado-Joseph disease experienced severe chronic pain in both feet cutaneous thermal change thermal hypersensitivity focal edema and sweating and had a history of bone fracture. These symptoms were compatible with a diagnosis of complex regional pain syndrome. After common analgesics failed to relieve his pain gabapentin was added and titrated to 2000 mg day 500 mg every six hours in less than two weeks. This relieved 40 of his pain and led to significant clinical improvement. Conclusions The pathophysiology of complex regional pain syndrome includes peripheral and central sensitizations the latter of which might be associated with the neurodegeneration in Machado-Joseph disease. In this report we suggest that gabapentin could inhibit central sensitization as an adjunct for complex regional pain syndrome in patients with Machado-Joseph disease.
