Hey Lena -
Well, basically, it's constant. It never stops. It's like a buzzing noise in my head, and it's on the right side, but when I plug my ears, I can hear it in my left as well.
My jaw pain has improved greatly in the last five months, but that's a result of frequent physio and massage therapy. I still have soreness, and neck pain, but it's much better than it was a while ago. My jaw muscles are still in spasm tho, and when I bring my teeth together, my teeth chatter because of the spasms.
I have started using a night splint (a nightguard) and it seems to be helping. I've only used it two weeks though, and my doctor said that it should take a couple weeks to take affect. He said that I have to keep coming in for adjustments every two to three weeks. That, and using physio, hopefully I will see the end of this nightmare.
I have gone to the ENT and he told me that my ear and hearing is fine. So it is definitely the TMJD that is causing the tinnitus. It's just a matter of time, I guess. Some people say that it can take up to a year, or even longer.
