Is it a heart attack or gas? While I was getting ready for work this morning I began with a sharp burn in my upper breast it has since radiated around and is under the breast near the rib cage. Some relief when I belch.
I had the same type of pains last year, and thought it was heart-related - it wasn't. My doctor sent me for tests to rule out gallstones, chest, etc. It was acid and I now take Pariet every morning, and it seems to be helping. Check with your doctor.
