hi i have been diagnosed with pernicous anemia 18 months ago and i have been on 3 monthly injections the whole time when i was diagnosed i was in a very bad place i had heart palpitations , blurry vison , pins and needles , negative thoughts , tireness the list gos on...i had to give up working as i coudnt cope.my iron levels had also become very low aswell. after loads of tests etc and the problems being found i have improved alot but 3 monthly injections just do not do it for me i am good after an injection for a couple of weeks or so. and then the symptons start to return i have suffererd terrible brain fog and pins and needles i have been to and throw the doctors on a regurlar basis pleading for more injections and keep getting no where. finally i took matters into my own hands and started to self inject hydrocoblim every other day to start in till i felt well i am now in a very good place with very few symptons and back at work. however due to a recent blood test showing my b12 level at 2000 due to the self injecting i went for my 3 monthly jab yesterday and was told by the nurse that the doctor as banned my injections for 6 months in which he will check my blood again to see if my level as droped signifently for him to reinstate my 3 monthly injections.as he said my level is dangerous? i am very upset as i am now finaly feeling well and need my 3 monthly as a maintanece jab to keep my level nice and high as this is working for me if i go 6 months with nothing i will be back where i started and very ill again. is this legal for the doctor to do this when i have pa? please can someone advise me what to do thanks.
