I have one other thing I'm not sure is a thing but think might be lol.

My arm is "relaxed" but the muscles seem to be doing things.

I do rub it to try to relieve the tension that is seemingly within it but it doesn't really do a huge amount.

I haven't had this particular symptom before and to be honest it is just quite odd to me. I can hold my arm out quite relaxed yet it appears to be "working".

I would really appreciate any input on this.

Thanks so much.
