Disabilitating pain that comes and goes that moved from left shoulder to both sides of neck, then right hand side mid back now its in lower right arm?

Pinched nerve: I would be concerned that your pain maybe coming from a pinched nerve in your neck. I would suggest seeing a neurologist, orthopedist or neurosurgeon for an evaluation and testing. This may include a MRI and an emg/ncs (nerve test ).

Myofascial?: This could be myofascial or muscular pain. The medical condition with widespread myofascial pain that charteristically does this is fibromyalgia. You evaluation will see if this is the problem: muscle tender sites, poor sleep, poor control of stress - these are some of the things we find.
