some of those symptoms {the upper body ones} made me think of Thoracic outlet syndrome{TOS} -but are you having any RSI
{repetitive strain injury}or hand arm problems? any falls or car wrecks/whiplash- hitting the head /neck or shoulders?

If not maybe some of it is vertebral artery symptoms?

I guess you'll know more after the doc goes over the MS testing with you.
