Just be told I have very low b 12 and given a prescription for b12 it comes in glass ampules and I have to self administer . I was given some blue needles also. Just wondering if I'm doing it right ? As I looked it up on YouTube and some people use two needles and some just the one?
I just draw up with one blue and give . Then I read something about glass shards so now I'm freaking out that I injected myself with glass shards ? What are your thoughts?
