I want to get tested for Pernicious Anemia. I've had pretty much all the symptoms for 7 years. Most concerning of all, to me, is brain damage (and tachycardia). I get about 950% of the Recommended Daily Intake of B12 naturally through my diet, as well as 250% of folate. Because the brain damage hasn't improved, it must mean that my body is unable to absorb the B12 I eat, right? I can't afford doctor's visits (not even regular checkups). I'm not on medicaid or any sort of assistance. There are no online lab testing locations near me. 1 - Is there a way I can get a test or diagnosis so I can get those B12 injections? 2 - Does anyone have information about B12 sub-lingual efficiency compared to injections, when there is neurological damage already? I'm in Maine, near Augusta. Thank you for your help!
