Sounds like you have a couple of things going on, and also sounds like there is some connection between the hands symptoms and your neck. Makes sense. Also, if you do need B12 (or specifically methylcobalamin), it is likely that your nerves are more susceptible to problems, and in that case sometimes manipulation can make a difference in symptoms without getting to the root of the problem.

Hmmm. And maybe you shouldn't be cracking your neck.

If it were me, I would continue with the methylcobalamin. If it's doing anything it is helping.
