I’m having similar problems! I had my gallbladder removed on 10/28/08 along with ERCP to remove stone in common duct, and have been suffering with what they call GERD ever since. Never had it before, though about a week before the surgery I started having a low level warm sensation in abdomen. Dr put me on pepcid, which they kept me on after surgery. It stopped working, so they put me on Prilosec which did nothing, now I’m on Prevacid which worked a bit, though not lately! I have a dr appt on Jan 30th and was told to stay on Prev and take one chewable Pepcid at night. I was also given sucralfate right after the surgery which is to bind bile, but it did nothing. So is this acid or bile? Did you have endoscopy before gallbladder surgery or after? Did you have stones? I’m at the point where I just wish medication would actually work – I don’t even care if I have to be on something the rest of my life. The pain is getting worse.
