Good afternoon, I have been experiencing a burning sensation in my tongue for a year now, as if I drank boiling water, pain behind the breastbone, occasional temperature rises to 37.0, and weakness. I've had numerous tests done, which showed slightly elevated GGT, small gallstones up to 0.7mm, normal thyroid function, and an endoscopy revealed reflux esophagitis! I completed a course of treatment prescribed by a gastroenterologist with no results, then consulted a neurologist who also prescribed treatment. All without success. I no longer know where to turn; perhaps someone can advise what to do with this unclear illness!!!!
