This is one of the many things that frustrates me about MS. I had pain like that for 3 years which my neuro explained as being caused by the MS lesions in my cervical spine. However, after 3 years of that, one of my MRIs showed impingement in just about the same area as the lesions, and I went to some physical therapy that included some manual traction that seemed to temporarily help (for a year) . Just this past autumn I went to a Pain Management place and got some cortisone help, and it definitely helped. So the frustrating thing is that I could have had less pain 3 years ago if only I had pursued the pain and not accepted that MS was the culprit. I hope you find relief - that radiating pain is no fun.
