Gi says I have ibs and constipation I'm having a burning sensation under my right rib gallbladder removed last year is it from ibs?

Could be. Hard to say for sure, because there is no formal testing for IBS. It certainly is not your gallbladder. It doesn't sound dangerous, and you should ask your doctors if it is appropriate for you to take medication for IBS. At least a trial to see if it helps. Hope this helps!
