Mostly I want to second the strong suggestion that you get your records. Not only do you need to have them, what they contain or don't contain may surprise you.

Regarding B12, please see my website (link below). The B12 test result may be normal (and in rare cases even quite strong) in spite of actual deficiency in the tissues where it must be do to any good. It would be unusual for symptoms to come on new and fast, but it does happen.

MS is not ruled out quickly, and one of the differentials is B12 deficiency, although you wouldn't know it by the way most doctors practice.

Both B12 deficiency and MS can cause serious problems before lesions will show on an MRI.
