Hope it turns out. The GE I saw a while back said a pain in the guts can be hard to find... you can feel pain in one spot and it may be actually being caused by sommat elsewhere in the guts. I once traced a leak in a roof of a Ferry Terminal building some 200 feet from ceiling stains and drips to the ingress point and it took two months... every time it would rain I would get more clues. Hope it takes your doc 2 minutes or less.
