Most people get TMJD from grinding their teeth at night. In that case, a specially made mout guard usually helps. I have EDS so my neck is curved the wrong way & the only treatment is physical therapy. Sometimes, you actual jaw could be out of whack & either botox or surgery will fix it. You should see a TMJ specialist to see what might be causing your jaw pain. If you’re in NY, I can tell you doctors for all of the above lol took me over 6 years of trial and error. Ice definitely helps! & a good arched pillow when you sleep. Also, make sure you’re watching your posture. Hope this helps you!

Have you been to the dentist to rule out any dental issue? They can also determine if you've been grinding. It can also be other dental issues so it's a good place to start. I have had both. Over the counter bite guards you form to fit your mouth work great and are cheaper alternative to dental bite guards from dentist. Also physical therapy helped me a ton! I leaned exercises and stretching for jaw. Wish we could post video here, I would share. Best of luck Feel better! ❤️

Only thing that helps my tmj is a muscle relaxer. I suspect it originated from taking antidepressants. I’ve been struggling with it since I was in my 20’s and I am 51 now. Acupuncture helped as well, but I can’t afford it. A chiropractor may help too.
