I have intense pain in my upper chest with only minor exhertion or after a heavy meal. I've been tested 3 times for heart conditions and G.I. disorders with everyone telling me, "everything is fine". There was one doctor (who no longer is with my HMO) who said that an xray reveiled that my large intestine was in the upper part of my chest by my shoulder. That's not where its supposed to be. Would this be causing the source of my chest pain?

I've had this for 2 years now and its getting debilitating.
