Background: Deafferentation pain is a subdivision of neuropathic pain that may complicate virtually any type of injury to the somatosensory system at any point along its course.1 Anesthesia dolorosa or deafferentation pain is felt in an area (usually in the face) which completely becomes numb to touch. The pain is described as constant, burning, aching, or severe.2 Case description: A 24-year-old male came with a complaint of severe pain in the left outer aspect of thigh and leg, which did not reduce with any medication. Ten years ago, he had undergone wound exploration for cut injury over the outer aspect of upper part of lower leg. Since then he had been having mild to moderate pain which increased in the past 1 year. His evaluation demonstrated neurofibroma of common peroneal nerve at the lacerated end. Excision of this was done to relieve the patient from pain but instead the pain increased. Examination of leg showed sensory and motor loss over the distribution of common peroneal nerve. Provisional diagnoses of, deafferentation pain of common peroneal nerve, with the differential diagnosis of complex regional pain syndrome (CRPS) type II,3 nerve entrapment, laceration of common peroneal nerve, stump neuroma were kept in mind. Conclusion: Deafferentation pain is difficult to treat. One has to be careful while dissecting the nerve during surgery, which may lead to deafferentation pain.
