Well the arm/hand/fingers could be some sort of RSI (from weightlifting and or /repetitive / desk work / lot of phone holding/crook of shoulder/neck? ) or sounds a bit like thoracic outlet syndrome, but the rest of the body is rarely affected unless you had TOS for a very long time.
*forward head/forward or hunched shoulders??

* sticky fascia /myofascial syndrome can eventually spread body wise as it the stuff that holds and wraps the inner body *

I don't knwo if it is all a single condition , or a combination, after reading more about TOS you might be able to tell if it might be a fit or not...
Many drs do not fully know about TOS, so if you think it might fit, find a TOS specialist..
