Has anyone else w/nighttime bruxism had a problem with biting their tongue? Several times in the last couple of months I've woken up with a mouth full of blood and a swollen tongue. OUCH! I keep telling my husband that sometimes my tongue just feels too big for my mouth. Strangely, I did a search (hard to do, because of the metaphorical use of the phrase) and ended up with researching tongue injury, which led me to macroglossia (enlarged tongue) which led me to hypothyroidism. That's right -- hypothyroidism! Apparently, macroglossia is a possible symptom of hypothyroidism. (Of course, it is a possible symptom of other things as well.) But it is kind of strange that a lot of symptoms come back to one of the areas that overlaps a lot of our problems. Anyway, I thought that was interesting. If anyone else has experience with biting their tongue (badly!), please let me know how you cope!
