SADLY I know all about TMJ. I have missed countless days of work, outings and holidays due to the pain caused by the TMJ. I'm fairly sure it was caused by three childhood concussions.
I wasted time and money with my dentist UNTIL he referred me to a specialist. I had severe issues and he never thought they warranted any further help. GRRRRRR.
After living a crappy, painful 30 years I found a GREAT/AWESOME doctor that has helped restore my sanity. I literally cried in her office when she explained my scans and x-rays and PROVED to me there WAS a major problem BUT it could be fixed!
I also have a GREAT physical therapist that has helped me (and basically tortured me) back to a normal I didn't even know existed. The throat pain is actually tight neck muscles and there's easy (but a little painful-yet worth doing) excersises that you can do to help reduce/eliminate the pain.
Have it looked at and good luck because it is fixable/manageable.
