I have heard of instances where B12 pills are taken and the blood count shows as fine, but the person still feels ill. Then they have injections and get suddenly much better. I would really like to try B12 injections, as I have constant neuropathy in my feet which stops me walking and standing, and am short of breath whether I use my inhalers or not. Do you know if my GP will prescribe injections or do I have to go private- and in which case, what sort of specialist should I see?
