my elder brother is always think that he has some problem in body. like throat is paining, stomach is paining, some ulcer in stomuch, 11 monnths back he did a endoscopy , since that day he was think that his nerve is damage & he has a major infection in his stomuch & his throat. again he did a endoscopy just 2 & half months back, and again he think he has mistaken, right now he is very upset & always tells that he is in big trouble, he always talks 2 the doctors & tell them the varius problems. his diet is normal.
