Could any G.P. explain the difficulty in prescribing enough B12 injections to alleviate symptoms of Pernicious Anaemia? My normally very kind and understanding G.P. becomes agitated and annoyed if I ask for an injection before 3 months,and suggests that I am imagining symptoms. (exhaustion, giddiness numb feet.etc.)It is beyond my comprehension that such a cheap and non-toxic vitamin should be withheld from patients who are feeling so ill...Please answer this---you are anonymous here!
