Interesting thread. One day I woke up in the middle of the night to tinnitus on both sides. I had not been exposed to any noise days prior to this happening. The next few days I noticed a stiff neck and limited rotation and occasionally clicking on the left side of my jaw when chewing. I went to 2 ENT's and explained my symptoms, they ran the hearing, MRI brain, MRI ears tests and nothing. They sent me home.
Month and a half later I still had ringing, mild but bothersome most of the time, especially when trying to sleep. I decided to to a different doctor, you know what they say, the 3rd time is the charm. I explained my symptoms to him showed him all my results, included blood lab results, he put his pinky fingers in my ears and had me open my mouth as wide as possible, he told me give your symptoms and how your jaw is opening I think its coming from a TMJ issue and send me to a specialist dentist and physical therapy. Took 2 weeks to see the dentist, he took a complete X-ray of my jaw and took X-rays of my TMJ joints. He told me they were not aligned correctly. I had a splint made which I started using, less than 2 weeks ago, after 1 week the T started to quiet down to the point its becoming less bothersome. They physical therapist touched some muscle inside my mouth top side and its very tender, not sure if that is playing a role. Anyway I think wearing the splint is helping, time will tell for sure, but so far after only 1 week the experience is positive. I hoping this resolves, going to bed one day fine, and waking up in the middle of the night is difficult to comprehend.
