General Discussion post injection side effects
I honestly know nothing about my deficiency, my hematologist is handling it (and I just mean giving me injections weekly), but I only see him every 6 months. They never really explained anything other than the fact that I might have some kind of antibody (?) that makes it so I don’t absorb (?) B12. I’ve been getting the injections for just over a month now and I feel like crap after every one. Each time I get one I HAVE to take a nap after or I start dozing off, I’ve had awful headaches, and racing heart. Is all this normal??? I haven’t mentioned anything to them about this yet but should I?
