What type of B12 do you take? Capsules? Tablets? Sublingual B12 (you put it under your tongue and it absorbs directly into the blood stream). I take sublingual every day. I had a severe B12 def. back in 1999 and only the sublingual brought my #'s up.

Since they said you had a TIA, did they do any clotting tests to see if that could've contributed. I don't want to make you dizzy but some clotting disorders, especially antiphospholipid antibody syndrome (APS) can go along with other autoimmune diseases. Have they checked your ProTime and INR?

Have you been tested for celiac disease? If not, please do! Having both a low Vit. D and B12 level would make me wonder about celiac disease. Go to the gluten forum and ask about it.

Watch out for foods that naturally contain MSG like tomatoes, yeast and cheeses. Those can bring on a migraine.

Sometimes doctors like quick fixes instead of having to think about something. If you don't feel good about a diagnosis or what they are doing, keep asking questions and asking for more ideas of what could be going on. It's your right! You pay them, they should give you a good service in return.

For the TIA, did they do a brain MRI to diagnose it?

I know it's hard to not push. I still have days when I do it cause I get so sick of not doing much!
