I'm new to this board. I have hypothyroidism and have been suffering from peripheral neuropathy for a couple of years. My B12 was checked a while ago and was 587 (197-866) and my folate was 20 (4.6-18.7). At the time I assumed all was fine, but now I'm not so sure. I've been taking high dose vitamins (including B12, but cyanocolabamin and probably not enough to treat a deficiency) for many months now. Initially, following a thyroxine increase too, my neuropathies improved and I stopped dropping things and was able to move properly, but recently have been getting worse again (but not as bad as before). I also know my T3 levels are low and that I'm not converting T4 to T3 well.
I recently started wondering if my folate levels being high would have given an abnormally high B12 reading - is that how it works? Could anyone give me any advice? I just don't know whether I have a B12 problem or whether its just all due to my thyroid.
Thanks for taking the time to read this.
