I have been diagnosed with TOS. Only because my pulse was lost on 1 artery during the test were they have you claspe your hand. I have a lot of pain in my neck and some in middle back and lower back. I want to have an xray done to rule out a disc bulge etc.... Maybe pressing on a nerve. I've had a head and neck mri a while ago but they were just looking for a tumor or something causing my dizzyness and cold feelings in head.

Anyway: do i need a xray or an mri?

thanks, merry christmas
