Approx 5 years ago I started to be treated 3 monthly with B12 injections after I'd had fatigue and a number of digestive problems low B12 for a while and been tested for PA (antibody test done twice showed I did not have it, although there is family history). Levels kept dropping despite the loading dose so I was given it every 3 months for a while. (I eat a good amount of meat.) Meanwhile I also tested low for ferritin and have eventually had 2 iron infusions (oral iron would not work well for me because of the effect on the stomach). Because of the oesophageal motility disorder I have, I have had numerous investigations which have confirmed that I do not have Crohn's or coeliac disease which might explain the low B12. Period blood loss could explain the low ferritin but I am sceptical about that. Have also had low vitamin D (not on supplementation) and have never had low folate officially, but has always been at the lower end of normal.
The other side of the picture is that I have had much more frequent migraines over the last year- now 2 per month, sometimes with vertigo & sickness which I first thought was benign positional vertigo. ENT and migraine specialist have now confirmed that they think it is migraine related vertigo. Also over the last year, I have found that the tiredness and brain fogs have come back in the last 6 weeks before a B12 jab, so with the agreement of the GP, am now having them every 6 weeks. Despite this regime, I am now getting frequent pins and needles, especially at night, and assume this is B12 related, though it is a new symptom for me. Have also had itchy feet which is odd for me, because although I have a history of atopic eczema, have never had it on my feet.
Anyone have any suggestions? Should I try folate supplemetation/ oral B12?
