Abstract
A major cause of lower leg pain after a stripping operation is due to the saphenous nerve injury. We report a case of severe lower leg pain, which was diagnosed as the complex regional pain syndrome (CRPS). A 43-year-old woman who had undergone the selective invagination stripping for the varicose veins of lower extremity presented a severe lower leg pain at 12-day after operation. The initial symptom was a stabbing pain and numbness localized around the ankle joint, with walking difficulty due to the pain. A saphenous nerve injury was suspected, although the severity and area of the pain changed over the period and not limited to the innervations of the saphenous nerve. She was referred to the orthopedist and diagnosed as CRPS type 1. If the patient presented a severe pain disproportional to the operative injury, we should consider the CRPS.
