I just had a pet scan and my doctor found a spot above my left kidney, about 2 centimeters. He has ordered a needle biopsy. All he told me was "it is uncomfortable". Has anyone had this done that can tell me what to expect? I am the type of person that gets very nervous and nauseated when I have to have something done. Guess I'm just a coward. Any insight would be greatly appreciated. All I have been told so far was tests for clotting before procedure and nothing to eat after midnight the night before.
