I have the same problems!! I am always so tense and I get pain in my back that wraps around into my ribs! My jaw was inflamed not to long ago because I was clenching my teeth so hard together when I slept. I finally got a mouth guard and it helped and now I don't clench my jaw at all anymore. But I have a lot of soreness like in my arms and in my back and the doctor said that my muscles are inflamed. It's scary at times because I get these pains in my chest and of course I think the worst. I have severe anxiety so I'm always really tense.

I do this and have a mouth guard i also get terrible pain in my neck and shoulders ive had tests, scans, mri, and im told its just anxiety. It is awful i cant seem to relax, ive had physio meds and im seeing a chiropractor but nothing seems to help.
