I've had TMJ and jaw arthritis since I was 15 and have undergone 2 major surgeries, and 2 minor surgeries. I am now 22 and have "the jaw of a 70 yr old" (Quotes from my doctor).
Surgeries help, but with day to day pain, it's best to stay away from drugs like Ibuprofen and Tylenol. They reallyyyy hurt your body and poison your liver!
I recommend seing a message therapist once in a while. Groupon.com usually has some good deals for your specific location. Also, I use this topical pain relief cream that works fast, smells great and doesn't harm your body. It's sold at Mintiva.com and they have different kinds for Back/Neck, TMJ, Tension, etc. They're having a sale too.
Good luck!!
