Background: Complex regional pain syndrome (CRPS) has been described as a painful condition with the appearance of trophic, vasomotor, and sudomotor changes. Most of the predisposing factors causing CRPS are classified. However, the definite cause of this syndrome is yet to be clearly specified in some cases. In this report, we presented a case with hand edema along with severe pain, diagnosed as CRPS type 1, coexisting with hepatitis B infection.
Case Report: This study presents a case of a 65-year-old man who had hand edema, severe pain, and decreased range of motion of the wrist without any constitutional symptoms and no history of trauma. He was diagnosed as CRPS type 1 after a detailed physical examination and diagnostic procedures. Ruling out other causes related to CRPS type 1, it is suggested that coexisting hepatitis B infection might be a possible triggering factor for this syndrome.
Conclusion: Hepatitis B infection may be a possible causative factor for CRPS type 1.
