I have an intense feeling exactly like when your foot falls asleep, only it runs from the back of my neck down to my waist along the right of my spine almost nonstop, for about 20 years, w/migraines and vision loss in left eye too. could this be ms?

This seems like a neurological condition. Hopefully, you have a primary care doctor and had a physical recently. That would help to rule out underlying conditions. There are several reasons for these symptoms; migraines, MS, Lyme disease, syphilis, but that is just a shortlist. See a neurologist

Hard to objectify your sequence of events, or precise cause, but intermittent migraines could affect vision if this comes and goes. Cause for your neck and back issues suggests spinal cord issues, but not fully classical. Yes, would also endorse a neurological consult but am skeptical about MS until proven to be so.
