Lauren,
see your dentist. You might be surprised that by just getting a bite splint to wear while sleeping could relieve some/most/all of your symptoms. Tmj is not a "death sentence." it can be "cured" and/or managed, but you have to educate yourself and take small, conservative steps to help yourself. A good tmj dentist can be a god-send.
I hope you get this checked out.
God bless...
Carol
p.S. If you don't think your family dentist is really all that good with tmj, go to a different dentist.
