Makes perfect sense dan, but in my case I'm tense 24/7. It has nothing to do with stress, or train of thought. My shoulders literally cannot relax without my concentrating on it, they automatically tense right up again as soon as my trainof thought changes. I've tested them... Like take right now for example; I'm chilling under a blankie, movie/series night... Tense as hell. Cos I dont have time to concentrate on my shoulders Guess I now know why I have neck problems too.
