I should mention that I have been taking an under the tongue supplement for B12 for over a week now after reading about how a B12 deficiency could cause PN. (Sort of self-medicated myself before seeing the doctor - bad, I know) But now perhaps the blood test results aren't showing a lack of B12 because of the 2500mg that I've been taking daily? Does it work that quickly?

I do take Nexium for heartburn and I've been taking it for 2 years. Apparently heartburn medication can cause a B12 deficiency, but again, I supposedly do not have one. That's the only medication I take.
