Oh my God almost all of this is spot on. I was suspecting that my physical posture was playing a role in my GP symptoms as well, and they have because I tried certain exercises that made my GP better, not completely resolved though. I also have been trying to treat myself with posture changes because I did notice that I have to forward head posture. Trying to do McKenzie exercises, such as horizontal chin tucks, significantly helped with jaw stiffness, and I’ve been doing them on a consistent basis but I noticed that even when I do them they’re not having the same affect anymore. Feels like I’m getting even more stiffer everywhere. But yeah I’d like to talk about it with you some more
