Autoimmunes predispose us to pernicious anemia, another autoimmune disease. I self diagnosed PA and my physicians assistant wisely sent me to a hematologist. Her tests showed that I do indeed have the definitive genetic and blood markers, requiring daily methylcobalamin injections. I have to buy this B12 from England, as we only have cyanocobalamin, the cheapest synthetic form, through insurance in the US.
My bloodwork has been the same for 20 years. Why on earth did none of the docs I’ve seen for neuropathy, difficulty walking, pain, fatigue, depression etc. notice the obvious?
Please advocate for yourself soon, before your symptoms become like mine!
