Have been waking up every morning with a burning pain in my stomach that seems to move to both sides under my rib cages. It feels like my gut is on fire. I have had a number of test. I have a Hiatal Hernia, GERDS, Barrett's Esophagus, and Diverticulitus. This burning pain is something new, it started about two weeks ago. I also have an anxiety problem and take Xanax 1mg. and Nexium 40mg for the GERDS.
