[65 and healthy]

I have stomach pain in the upper right which started after dental work. Although I tried to be "brave" during the three hour procedure, I was miserable and tears flowed freely. I was not in physical pain, mostly it was fear. After ther procedure, my stomach began to hurt a lot. I think I may have burned a hole in it from all of the acid I produced during the procedure. Is that likely? Or, could it be from the medication? Other thoughts? Thanks for helping.
