Also, you might go to a dentist specializing in TMJ disorders or a maxillofacial specialist, because a problem with the
jaw is strongly suspect with headache
on the
side with
jaw pain. Do you clench or grind your teeth when you sleep? I'm a clencher myself and I have both joints with arthritis and joint disc dislocations, with one of them out of place even when I open my mouth (called without reduction, I believe).
