I have been recovering from a major op 5 months ago and still feeling v tired, have hair loss, am very forgetful and have had tinnitus for 3 months. I have been on iron tablets and Vit D for a while but am not quite right. As part of a test for my iron my B12 was measured. It was 225. Although this is above the lower limit I have read that it should be between 400-500. Is this something I should be raising with my Doctor.
Does anyone have any experience of low B12 and any advice?
TIA
