After 6 injections and one 3 monthly injection, my B12 raised from 190 to 335. I think it is still low and I do have neurological symptoms (my left side is numb -almost paralysed), tinnitus and I can't sleep at nights. My neurological symptoms got better after the 6 injections and they returned after a month or so. When I had the 3 monthly injections, it was still not enough and the symptoms came back after a month. That is why I tried B12 patches and Feroglobin. I have a phone appointment with my GP on Friday. How much would you expect the B12 to be after the treatment? I so much fear the GP is going to say that I don't need the injections any more. In fact, I desperately need them! I also have Hashimoto and I believe I need to be on the top of the range. Is this right? Thank you!
