Are you being treated for H. Pylori? I have wondered which antibiotic is used for ulcers.

Years ago got a burned esophogeal sphincter (i.e. an ulcer of sorts). Incredibly painful. I am sure stress was involved along with my awful diet - not the bacterium which causes stomach ulcers. We used to pop Tums and Rolaids like they were candy, until we quit eating Pizza and some other irritating foods. No problem now.
