Hi, i'm new here. I was feeling really unwell last year visited doctor in July and was diagnosed with pernicious anaemia and b12 deficiancey. I had loading doses and 12 weeks later first of what i thought were lifelong jabs. However my doctor did blood test in November which showed i had gone from 109 to 2000. He said i didn't need any injections at the moment to have another blood test in 12 months. So why am now feeling unwell again, went back to doctor, and am awaiting result of fbc and b12 blood test. I'm confused.
