I had my gallbladder out 1028/08 and have had a burning sensation in my stomach and chest/back throat ever since. It moves around, sometimes only in stomach, etc. Had ERCP at same time as surgery for stone stuck in common duct. Dr. did ANOTHER ERCP last week - he was sure there was another partial blockage. There was nothing! Now burning pain is worse than ever - I've been on Prilosec, Prevacid, Zegerid, reglan, sucralfate, etc. either got no relief or got worse. Dr. said there was no evidence of GERD during last week's ERCP. I am in constant pain, though I'm able to sleep. Could there be a problem with bile flow? I don't have any lower bowel problems, just the burning and intermittent attacks of burping, upper chest trapped gas. I'm eating small amounts of low fat food, never overeat, I've tried digestive enzymes and natural supplements. Nothing helps and and since ERCP the burning is worse.
