Oh, please go to ER or an Urgent Care Facility !!!
I'm so sorry, i had the opposite with EPS - yawns that shook my whole body, and frequent. and trouble swallowing. so i can sorta relate.
but this sounds very disturbing - it is impeding your movement terribly... please get help !
( gosh, it's funny, we are giving each other the same advice... rofl
)
anyway i'm serious about the jaw. if it doesn't feel better within 24 hours at least, go in.
