I was diagnosed with PA around January and had my 6 loading injections of cyanocobalamin ending 11 days ago. Now I am prescribed monthly injections. I was also anemic at the time I was diagnosed. 4 days ago I started getting headaches, nosebleeds, feeling dizzy, fatigued, and like I'm in a dream. I am just wondering, is this because I don't have high enough b12 levels to go more than a week without an injection? Is there a way to help not feel so poorly? Any advice helps. Thank you!
