Well I have been diagnosed with a gall bladder stone, have had an endoscopy and ok anyway it was the up the butt one, and down the throat, about 6 mo ago, what I'm experienceing is on the other side, being it my left side, just under my rib cage is a tender spot I believe it to be my intestines, and its progressed to the point where it seem to be from side to side across my mid section, again just under my rib cage. I have started taking advil 200mg, because I don't like to feel the presence, its not a pain but somethings there, I had a ex ray done, just on the premise that something is there, but they said no, just gall bladder stone.
