I have been getting this (quite painful) tingling feeling in my back. It sort of feels like pins and needles, but more painful. It last only a minute and happens maybe once every few weeks, but I was wondering if it could possibly be related to my low B12. My last blood test said my levels were at 93 and I read that it when it's so low, it can cause neurological issues.
I have noticed slight tingling/numbness in my pinky fingers (weird, I know) from time to time, but nothing else similar to what I get on my back. Could it be related?
