Painful legs and moving toes.

A 40-year-old woman reported involuntary and irregular movements of her left toes accompanied by pain. This arose following arthroscopy after a sprained left ankle. She had involuntary flexion-extension and abduction and adduction movements of the hallux and the other toes, with reduced pinprick sensation on the skin web between the left hallux and the second toe. Nerve conduction studies confirmed a deep peroneal nerve axonal injury. We diagnosed the syndrome of painful legs and moving toes, provoked by a peripheral nerve injury. Her symptoms have persisted despite pregabalin, gabapentin and amitriptyline.
