Try putting you finger on the bone
the ear, open and shut the jaw
, does it feel funny, hurt, or make a "cracking" noise. Are you ears plugged of feel full. There are so many TMJ symptoms, I can not begin to list them, but, it sure can cause jaw pain, in fact, it can sometimes even cause upper chest pain. I would see an orthodontist, he will run some tests on the jaw area and be able to tell you more of what is going on.
