I'm in limbo, and while I don't have neck
pain that is associated with sudden neck
or head movements, I do have neck
pain that feels like a "kink" in the neck
that can last a month or more. I don't know if it's associated with everything else, I usually wake up with it, but I have heard people with MS talk about spasticity in the neck
Not sure if that helps at all, but hey, I'm trying!
