Well I just wanted you to know I have the same tightening of the face as you do. I have gone through allot of testing including a cat scan of my brain and so forth. My doctor says I am healthy I know I do have anxiety and I make my muscles tighten. If i'm not thinking about it its not there. Also I was told by a ENT I have TMJ so I put warm compresses on my cheeks it helps believe it or not. I am 56 years old but everyone says I look 40 so I'm telling you relax and you will see a difference. Try the warm or hot compresses and hang in there.
