Saw my primary Dr. today and what an awakening!

He was not at all surprised on the burning feet, combined with the rest of the symptoms, that I most probably have a deficiency of B12. He advised me to continue the sublingual methylcobalamin (1000mcg) and to call him in sixty days with a report of how I'm doing, stating that if I feel no improvement, we would be checking methylmalonic acid, and antibodies to intrinsic factor and parietal cells.

As to the potassium, he said he would need to go to his books to answer the question I asked here, then went on to state that if the orthostatic dizziness persisted he would be keen to do some tests on cortisol levels and other corticosteroids. I seem to have a family practice Dr. who truly is on top of this and, yeah, I am amazed!

I've only been on the methyl B for (Jarrow) six days and I know this will be an up and down process. I'm digging in for the long haul.
