A 54-year-old woman presented with a 1-month history of pain and numbness in both feet. She had taken metronidazole for over 4 years previously to treat vaginitis. On nerve conduction studies (NCS), neither the sural nor right superficial peroneal nerve (SPN) was evoked, nor did the left SPN have small amplitude, suggesting axonal peripheral polyneuropathy with sensory fiber involvement. When she restarted metronidazole, she immediately complained of recurrent paresthesia of the feet. We performed three electromyography (EMG) studies and followed the patient for 6 months.
