I am becoming more and more convinced that I have a functional B12 deficiency and will be arranging an active B12 test in short order. However, I am also currently being treated for iron deficiency (ferritin of 4) and despite starting on ferrous fumarate 305mg once a day I do not feel better; if anything I feel worse. I am also being treated for hypothyroidism of nearly 20 years' standing.
My question is whether cyanosis of the fingertips is specific only to iron deficiency or can it occur with B12 deficiency too? I still try to go running, which is probably foolish, and my fingertips turn blue in less and less time. They went blue while walking fast yesterday too, so this would appear to be getting worse.
I would also like to ask members about incontinence. I go through phases of suddenly feeling a desperate need to go to the toilet and never quite making it before I start to leak; as yet I have not completely wet myself but I'm worried that it may not be far off Is this something that others have been through.
I would prefer not to have a B12 deficiency if at all possible, but given that the iron pills are not making me feel better and I am getting more frequent episodes of dizziness, 'the gulps' (do you get those with iron deficiency too?), clumsiness, forgetfulness, irritability and stopping mid sentence because I can't for the life of me recall the word that I need to use I do wonder...
