Well,I've had a large numb area on the back of my neck down btw my shoulder blades that's been like that for about 2 and a half years or so I though to myself that's weird and just didn't really think about much more and went on with my life until I was dx'ed with ON and then I started doing research about MS and read about Numbness being a symptom and I have two lesions in my C-spine one is btw C-2 and C-3 and so I assume that's why the numbness is right there and I know that's it's permenant it's been longer than 2 and a half years so I assume the feeling is gone forever.
