mrsD - thank you kindly for your response.
Yes I had my B12 level tested twice - both times around 485 pg/ml.
I am still taking sublingual methylcobalamin 1000 mcg and folic acid daily.
I will look into the special MRI you mentioned to visualized the dorsal root ganglia.
I do not experience any swelling.
I am trying very hard to get off the 0.5 mg of Ativan I take at bedtime. I am trying herbal teas etc.. as a substitute. I do not want to be on any rx medication if I can avoid it.
I do take Magnesium Taurate 200 mg with dinner. I haven't noticed any effects from it.
As an FYI - I am very sensitive to medications in general. I am lucky if I can tolerate a new med. We went through so many meds when this all started (Lyrica, Prednisone, Ambien, Restoril, Vistaril, Elavil) none of which I could tolerate for various reasons. I cannot take anticholinergics at all.

I am meeting with my neurologist (neuromuscular specialist) next Tuesday - he wants to recheck all my IgG and IgM antibodies for Guillan-Barre that were all negative back in November 2012. Anything else worth asking about or checking while I'm there?

Also how do you make a new post on this forum and send a private message to a user?

Thanks!
