Does anyone else do this? Consciously tensing muscles....

[HereIGoAgain]

Hi all

Not sure if this is the right place to post this but I'll give it a shot (might be a GA/OCD post). I have this thing where I constantly feel the need to tense my back/chest for literally a second (if even) and then after a few seconds do it again. It's driving me round the bend.  I can't seem to stop doing it and the more I try to stop the more I do it. It's like I need to keep constantly tensing up. Does anyone else get this? 

Wondering if this is an anxiety symptom or just part of my general craziness lol

I am constantly tensing my muscles but not on purpose. I usually don't even notice I'm doing this until someone points it out (like my chiropractor) or when I am doing guided muscle relaxtion exercises..then I really am surprised how tense I am all over!!!
