My tongue, gums and teeth burn, tingle or ache at various intensities during the day but never lets up. Chewing gum gives me relief...probably because it masks the burning discomfort. I also suffer from imbalance and a sense of unsteadiness. My brain feels like it's "floating"or "bouncing around" to the point that I find it difficult to focus in on something with my eyes unless I'm totally still. Can you suggest what might be going on ? No one seems to have any solution.
