I have had a few tongue ulcers and terrible burning on my tongue & throat going on 4 weeks. Burning in my tongue driving me crazy! Started 2 weeks after getting off antibiotics for Proteus mirabilis urinary infection. Now I have yellow mucousy burning diarrhea. Reduced to eating yogurt, eggs & mashed potatoes. Anything else burns. Tried Carafate, Mylanta, slippery elm, vitamin b12, folic acid. Now on prednisone. Only relief I have gotten has been from taking a low dose of Xanax. I have history of Crohn s. Also once treated many years ago for h pylori. Could it be a hiatal hernia? Can t get into GI doctor until next month. Any suggestions? Thanks.
