Thanks, yes the thought of a new doc has crossed my mind. Funny, I know what testing I think I need now but I also need a strategy to convince him. Bottom line is I will look elsewhere if I have to. Not sure right now where to look or who will listen. I'll cross that bridge when I come to it (which might be soon). The neurology department is short of docs so I couldn't get an appointment until Oct 28. That's so far off that I requested at least a telephone consultation this coming week. I plan to ask for testing asap in at least the following areas: Flouroquinolone toxicity (because of the Levaquin I took), more aggressive for hypothyroidism (my borderline TSH levels), A1C, and small fiber skin biopsy. By the way, I just started the B12 methyl cobalamine (5000 mcg/day), my B12 lab was 339 which is on the low side.
