A 16 year old boy had continuous pain in the right testis, groin, and the medial aspect of the thigh and knee for 16 months.The onset of symptoms was acute and pain distribution included a retrograde area in relation to the entrapment site. Tinel's sign was the clue for diagnosis. Diagnosis was confirmed at operation and division of the aponeurosis of Hunter's canal relieved the symptoms for three days. A second surgical exploration, proximal to the former one, was performed after five months.The right femoral nerve was found normal. This new operation was therapeutically ineffective. Causes of pain distribution and relapsed pain are discussed. The relapse was attributed to myofascial pain syndrome. This diagnosis should be considered independently of the correct treatment of the primary lesion.
