Hi there, thanks for responding.
I know for certain that they have tested everything except the MMA, which was all a negative, but I can ask about that when I see her in January. I definitely don't have a b12 deficiency of any kind, beyond not absorbing the stuff from food and needing my daily supplement. I remember what it feels like to be b12 deficient and my neuropathy feels different to that.
My latest blood test showed a big drop in my wbc, but he is assuming that is just a dud test because there was nothing else to be alarmed about, which will be confirmed in a few weeks when I go back again. TSH is still extremely suppressed and symptoms are the same - worse at the moment as I feel like I am catching a cold quite often and the mouth ulcers are a pain in the butt.
My MCV is still a only touch above normal, which is excellent, so if those reticulocytes eventually get their act together I should be in the clear.
Thanks again and hope you are well also
