""my neck was really out""
"" i had no feeling in the fingertips of my index and middle fingers on my left hand.""
Lulu - that's a job for a chiropractor.
They're training is for exactly what you describe.

The numbness in the fingers is from pinched nerve.
Chiropractors job is to unpinch nerves by aligning the bones properly.
Though your fast would help eat up any bone spurs, which is a build up of calcium.
