Hi there
I had B12 deficiency diagnosed a couple of years ago, and as it wasn’t diet related, my GP put me on lifelong B12 injections even though he didn’t feel I really needed them as IFA was negative (this was in Hull following HEY guidelines I suppose). He was very dismissive of my neurological symptoms - foggy headed, forgetful, balance issues with lots of falls (I’m in my 40s) and problems with my sight. He put me on standard 6 loading doses followed by quarterly injections. He wouldn’t increase them despite my being desperate for further injections after just over a month.
I have now moved house to a different area and changed GP. They did a B12 test which showed my B12 at over 1000, and with parietal cell antibodies normal, they have now refused to continue my injections. I was supplementing to a degree with B12 sublingual spray and it was about 3 months after my previous injection. However I had been getting very worrying symptoms including electric shock type feelings in my hands and feet, weakness, really bad brain fog, anxiety and inability to sleep, pins and needles and occasional total loss of feeling in my hands and/or feet with pain - sometimes only partial as it felt like I was walking on sharp stones for example. Oh and of course the ever present fatigue!
The doctor did a vit D test which was normal. I requested copies of my blood tests, so I have all the recent ones, though not the original ones from before changing GP.
I was told to stop taking any B12 for 8 weeks and come back for another test, but I wasn’t happy about this. I have since got a nasal spray and more sublingual liquid, and I have been using those with a multivitamin, folic acid high strength and a vitamin pill containing Zinc, magnesium citrate at a low dose and B6, and adding magnesium oil spray occasionally which does seem to help me sleep. My symptoms have improved a great deal, but not completely.
I have been to my GP today and told him that I believe that as my B12 deficiency is non diet related that I should be on lifelong injections, he has agreed to refer me to the Consultant Haematologist for further tests but this will take a couple of months, and I wonder if the supplements I’ve been taking will impact on any results and mean I won’t be able to get a diagnosis. He won’t allow me to have a B12 injection while I am waiting despite tingling in hands and feet, and won’t support me to self inject by allowing someone from the practice to show me how to do it safely. I am after some advice on what I can say to the haematologist if as I suspect, my blood results are skewed by the B12 I am taking.
Sorry for the long post and I really do appreciate any help you can give me!
