Hi, I have neuropathy and other symptoms including hair loss which has gotten better since I've had the injections. My neurologist says I'm B12 deficient, I have had 10 weekly injections of 1000mcg each. I've seen a hematologist, my intrinsic factor is fine. All vitamins have been checked etc.and thyroid checked ALL thyroid tests normal also no antibioties. I am now just starting weekly a nose spray Nascobal 500mcg a week, (prescription only here in the US and expensive) they claim will work just as well. I'm just wondering if anyone else is using this? My B12 is now 800, it was 230 before injections (range is 200-1000). I still have anxiety/depression which I think may be partially because of birth control pills. I also take magnesium, folate, iron. The hematologist doesn't think the neuropathy is from B12.......I'm only 21 and sick of the run around!
