This is going to sound very stupid, but please bear with me as its true.
When I wake up in the morning my jaw is fine. As they day progresses something seems to happen to it.. (since I have pain in one side near my ear when I eat etc, I assume it's something to do with the muscle tensing up perhaps?).. And after being up for a few hours my jaw/teeth no longer fit together properly.
It's only started happening the last few days or so, but it's a horrible horrible feeling.
Anyone else had this? What is it?
