So last night I woke up because I had bit my tongue. It wasn't just the sides.. My teeth like clamped down on my tongue... I've never had this before.. But I know I've seen this before on an *** forum.... Is tongue biting a later symptom... Has anybody else done this before... I know that my jaw is usually very tight during the day because I'm a tense person... Maybe I was grinding my teeth or going to snore.. I don't know...
