For the last 2 nights after supper, I have had pain
in the left side, under my breast, going to my back, and heartburn; If it had been on my right side, I would have thought it was the gallbladder. After I took Pepto-Bismol AND Tums, it eventually went away. Last night it happened again, after supper, but this time the pain also went into my left arm down to my elbow. I took the Pepto as before, then started thinking maybe heart?
