Thanks so much EVERYONE! I am not totally convinced I have TMJ..... just when I tried to google jaw/ear pain it kept coming up so I thought I'd ask some questions and see if anyone knew anything.
Can it just 'come on' like over night with no history of it ever before?
I have been chewing a lot of gum lately, a pack every 2 days at least and usually 2 pieces at a time. Its sugarfree!

I have had my wisdom teeth taken out, all 4 when I was 17 (15 years ago YIKES!) and never any problems with that.
TMJ seems a bit of a far reach for having jaw/ear pain for one day to my logical mind, but I don't know how it starts or when it starts.
I also woke up with the tendenitis in my wrist acting up and hurting also. I don't know if they are related... if I hurt myself sleeping funny last night or something.... its all just so weird!
