What was your B-12 number from bloodwork? Approx six months ago I woke up with sore calves and few days later tingling in feet forearms and calves. Went to doc and they tested for B-12 and was 190 which from what I understand anything under 200 is considered deficient especially if it has been there for awhile. Fast for ward to today and I do have many of the symptoms you describe. Lots of nerve pain full body tingling including face. I do have some neuropathy I am being treated for in the feet but minor. I guess low B-12 can damage nerves. Has your doc given you a shot and are you on oral supplements??
