It’s like my skeletal muscles are all tight

Weird reaction but I guess it’s all connected. One things happens in spine and the rest of the muscles react. I’ve noticed that it’s like my inner most layer of muscle tissue is always tight in my throat, chest, ribcage, diaphragm. Stretching helps ofc. But I sure would love to figure out a better remedy to this. Taking enbrel rn. It helps but I still flare up. I try yoga, exercising, back workouts (gently ofc), and running. Seems to help too. But I dunno. I’m just tired of being all tight. It’s like it causes my already kinda anxious prone mind to be convinced that it’s always time to be anxious. Mind body connection. Sheesh.
