hi kevin,
for the last year or two or longer? i get inflamed tongue bumps, doesn't look like much (just an inflamed bump here or there), but boy do they hurt. not sure what causes them, but never used to get them. and sometimes sores in other parts of my mouth and i wonder if i did something dumb and just don't remember, but they seem to happen too frequently and never used to happen, so i wonder if its all connected. i wonder too, am i dehydrated? is that doing it? or is it autoimmune? or endocrine related? i've asked doctors, but no one is very sure.
as for dry mouth, mine is caused by the muscle relaxant, zanaflex, that i take. its not too bad though if i drink a full glass of water when i take the zanaflex, and if i'm awake an hour later when the side effects start to kick in, drink another glass or two or three. could it be medication related for you? if so, drinking more might help like it does for me. if its autoimmune related, i imagine that it could be harder to "fix".
