It sounds to me like you need an MRI of your cervical spine. Have you had one?? I may have missed something, as I haven't been here very long.

The MRI should be with and without contrast material so they won't miss anything. See your doctor as soon as possible, as your neck could very well be causing the problems in your arms & hands. It does with mine. Best of luck and let us know. God bless. Hugs, Lee
