I have had pain in my upper right abdomen that comes and goes throughout the day for the last 3 months. Sometimes the pain is acute. ER Dr. suspected gallbladder but all blood tests were normal and ultrasound was normal. Had a pos. H.pylori blood test so went on antibiotic treatment. Had an endoscopy which showed no abnormalities or ulcers. The baffling thing is this: the pain is very intense WHILE I am eating sweet things like pineapple or fruit juice etc. (and even, actually,especially, artificially sweetened gum). I am not talking about a few hours later I am talking right when I swallow. Any Dr. I have told this to has treated me like an idiot, and yes, I have found NOTHING in the entire www, but IT IS HAPPENING, IT IS THE TRUTH! I cannot simply avoid certain foods as the pain is there regardless, it is just magnified when eating sweets. The ER dr. suspected shpincter of Oddi disorder (even though I have never had my gallbladder removed) but the surgeon he sent me to dismissed this on the basis of my normal blood tests. Please help. btw, I am 43yr female in otherwise excellent health and mostly vegan.
