Saw my GP Monday and to my surprise he really listened and was open to B12 injections, even if b12 levels are "ok". I've had blood taken for FBC, full iron (says ferritin doesn't tell you anything), folate, b12 and IFA. He says we need to ensure folate levels are high enough before starting b12 and that I might need to supplement with that first. Us that correct? He did say that he didn't want to start injections unless absolutely necessary as they would be for life, although it wasn't a problem. He said that after one injection I may be able to keep the levels up with tablets. It definitely helped that my husband was there and could confirm my balance problems and also that I have a chest infection and dizziness at the moment. So all in all quite positive, although I wonder about the folate.
