Hi All. Not unduly concerned because all my other bloods are good - but I recently requested my B12, Folate and Ferritin plus blood glucose all be checked due to new additional pins and needles the length of both arms on top of going numb everywhere, including face. I’m hypothyroid and have Sjögren’s but supposedly the Hypothyroidism is well controlled with Levothyroxine (Synthroid) which I’ve been on varying doses of for many years. I’m in Scotland, UK

When my SFN first started it was suggested to me on a UK thyroid community, that I might have pernicious anemia. I was on Methotrexate, folic acid and Plaquenil at the time so got my homocysteine and MMA levels tested - all within range as was B12 (444). But my vitamin D levels were low so my GP agreed to prescribe me AdCal D3. I did some research and decided that there was no harm to be had by taking a B12 sublingually daily.

Cut to five years on and each time my B12 levels have been checked they have been progressively higher. Now they are at 1,485 which is pretty high. But I haven’t been taking B12 on a regular basis for a few years? And my GP - who ordered these tests - merely remarked that my levels were very good.

Can anyone advise on the possible significance of this please?
