I suffered from burning tongue, and not one doctor took me seriously. Did some research and learned that the blasted medication prescribed by the then-neurologist was behind my suffering. Burning tongue and totally dry mouth. Was so difficult to deal with since I was a language teacher in a high school setting, teaching 6 classes per day. Had to have bottled water placed in various areas of my classroom (I did not stand still while I taught, since I enjoyed interacting with the students). Became intensely bad until I insisted that I would no longer take certain medications, went to another neurologist who crated a tapering schedule for me. Still had periodic episodes of burning tongue but so much milder. Hurt nonetheless. Chips of ice was/is so soothing. Used to chew gum but that created issues with my partial so used non-methylated cough drops/lozenges instead. Over time, the condition ameliorated, and presently I experience it mostly when not sufficiently hydrated. I also learned within the past few months that there is a connection with burning mouth syndrome and a lack of certain essential vitamins, I believe it's the B family. I've been on B12 injections monthly (prescribed by a neurologist who was consulted due to my having so many neurological problems), for nearly 9 yrs now. I gather that those injections contributed to my having obtained relief from my painful symptoms.
