Hi Devon,
I don't have TMJ but i do get the ear popping thingy.. It used to make my panic worse, thinking i had an inner ear infection but i had my ears checked and i turned out fine... I think you'll find that alot of panic sufferers do experience ear problems... is it related? i don't know but i do know that it's quite commonn.. AND, you have TMJ so i'm sure the two go hand in hand.. See a doc just to make sure that your ears are healthy, just to be on the safe side..
Love,
