Hello,
I just looked thru your other posts and found your symptoms-

[I have constant neck pain, headaches, pain that radiates down my right arm, whenever I am not laying down the muscles spasm across the top of my shoulder & lower back, numbness & tingling in my hands & from my chin down my chest that comes & goes.]

do you do repetitive work or lots of computer work??
hunched or rounded shoulders?? are shoulders level and even ?
or even previous falls, sports injury or car accident?
{whiplash or neck/shoulder injury}

If any of these fit you might want to read on our TOS forum -
useful sticky thread- http://neurotalk.psychcentral.com/thread84.html

here are a few starter links about Thoracic Outlet Syndrome

many with TOS have minimal things on our MRIs but those are not the cause of our pain either.

Just wanted to let you know about it just in case it fits.
