I was under enormous stress when the pains started and the fear that it was cardiac
in origin added to it. I had the
nitroglycerin sublingual tablets. I took them, sometimes they helped, other times they didn't. To this day I have no definitive answer as to the cause of my pains, but they seem to have subsided for the past 6-7 months. Try the nitro and see if it helps. My guess is that it won't help indigestion, but would if it was due to vasospasm or other cardiac cause.
