about two weeks ago I experienced some chest pain between the breasts. It came after I ate way too much on an outing. I am 61 years old, female, and in excellent health. The pain came quickly and radiated into my back. By the next morning I just felt generally ill. I went to my doctor and an EKG was done.....it showed a rapid heart beat, but I also had a fever and he felt the heart beat was due to infection. I had a total CBC and everything was normal. I have these pains sporadically, maybe every other day and it usually follows eating. I have lost ten pounds in two weeks because I am afraid to eat very much. I had an ultra sound on my gall bladder and it showed no stones. What could this pain be from. I doesn't last long, maybe three or four minutes when it happens, then it disappears. I am totally confused.
