Re: Tinnitus after neck strain or tmj?
Sorry to hear about the tinnitus - it can be so aggravating. People don't really understand how bothersome it can be until they experience the joys of constant screech-in-the-head for themselves.
This is a tricky one and there's not a lot of research out on this, but from what I've read and from my own personal experience, it seems that TMD symptoms after dental visits are related more to the strain of having your mouth cracked wide open for extended periods of time than anything else.
I only had chronic headaches before an unsuccessful and tricky route canal (where I had my mouth wide open for 2+ hrs) which lead to a series of dental visits. The dental visits seemed to be the match that ignited the full spectrum of TMD symptoms for me, including tinnitus and hyperacusis. Even now, my tinnitus and head pain flare up after dental visit. I saw my dentist yesterday and the usual dull hiss of tinnitus was more like a roar for the rest of the day. I'm now in phase two - braces - and after a couple years of severe pain, I finally started to feel better after several months in my repositional splint.
I see the muscles of the head and neck like an interconnected galaxy of sorts...your ears, jaw, shoulders, neck seem like separate entities but they are all affect eachother, woven together by muscles. With TMJ, muscle issues can create a constellation of symptoms (muscles can do this on their own or because of a structural issue) and if trigger points are formed, sometimes this constellation gets locked up and is difficult to disband without addressing the triggerpoints.
Sounds like it's early days for you and I hope your reaction is a temporary one due dental work only. You could try seeing a cranial sacral therapist, getting massage, visiting a PT who specializes in TMJ/head and neck issues or an acupuncturist to help ease your symptoms. If you have anxiety, you may be clenching without realizing it and that could also be contributing to your situation. Stress is a big contributor to issues in the shoulders, neck and jaw. I have found that learning to deal with my anxiety has greatly helped in reducing my pain and my clenching.
Best of luck to you!
