Vitamin B12 and Neuropathy

I went to my Neurologist and saw the nurse, because my neurologist had to cancel all her appointments. The nurse went thru all my blood work, and said my B12 is way too low for someone with Neuropathy. She repeated that B12 test, and again it is low. Because it is in a low, but normal range, 2 neurologists, 2 pain specialists, and 1 primary care physician of mine, did not catch that it was low. Only this nurse did, and now I need a week of daily Vitamin B12 shots, and then weekly, for a month. If you have neuropathy, B12 level should be at least at 400. Mine is at 185. I am praying Vitamin B12 helps. I really know nothing about Vitamin B12. Just found out mine is way too low for neuropathy. These doctors need to read the actual numbers, not just the highlights of what blood work is out of range. Maybe this could have been caught 2 years ago. I don't know if Vitamin B12 will help, but I am giving it a try. We all go thru so much.... Lori Renee
