I had a long list of what my burning mouth started after. The diagnosis of reflux ( silent) and Barrett’s was so far removed from items on my list. I am wondering if coating your mouth and tongue while taking sucralfate liquid to coat esophagus makes a difference in the metal taste after using it for a couple of months along with a ppi. I certainly found my miracle reflux treatment for my burning mouth and metal taste and overly sensitive nose smells.
