I was diagnosed with PA about a month and a half ago after many appointments and blood tests. Since I live in the US, I was prescribed weekly injections of cyanocobalomin for 6 weeks, then one injection a month for the rest of my life. Retesting for IFA and B12 levels after 5 weeks. I am also anemic from the PA and my worst symptom is fatigue. I can't do anything without having to take a nap. I have been on the injections and iron supplements for 3 weeks now and was wondering if this will ever go away?
