I'm sorry you have had to go through all of this, but glad it sounds like you are feeling much better. Re the jaw...since I don't know why, my experience may not relate at all, but I have TMJ (Temporal Mandibular Joint Syndrome), and when having an episode, my bite changes - lower jaw shifts forward and to the right, so that I can no longer open and close my mouth properly (front teeth end up touching, back teeth can not..really a weird feeling!). This comes with a good amount of soreness in the jaw (where the jaw has shifted so it's not seated properly on the skull)and I'm unable to eat more than very soft foods as I can't chew.
I've had good success in treating this with warm moist compresses to the area that is sore (thank goodness I only "unhinge" on one side) and take tylenol and it resolves within a couple of days.
Worth a try for you perhaps?
ps as funky as the above sounds, you can't tell from looking at me, that the jaw has shifted etc. Thank heavens!
hth, and I hope you will not need surgery,
