Hi, A few years back I was diagnosed with having Pernicious Anaemia. I was given injections to begin with and then after that I was told I would not need anymore. I recently visited my Haematologist and he was rather abrupt by saying that my B12 test indicated that they were very, very low and that I have not been getting my injections at my GP. They have started to administer the 5 important injections and they have said they will make sure that I get them regularly now and that it will be for life. I just wanted to ask whether it is for life? I don't mind injections but I never thought it was as serious as my Haematologist mentioned. My GP said that after the first five because the levels went high, he said I wouldn't need anymore, but they don't seem to have lasted long. Where does the B12 go? Dalekteacher.
