Hi,

I will post more later, but my wife has had extreme sciatica with no compression or identifiable cause (except trauma) for about 5 mos. now. She is 30. She was also just diagnosed with small fiber neuropathy, but she never had any neuropathic issues before she fell in April. One thing I notice is that her B12 levels are EXTREMELY low (she has had so much bloodwork done in the past few months). I wonder if it's affecting her ability to heal. Her docs say that everything is "normal" -- including her thyroid hormone levels, but I also think there's something up there.

Her B12 serum result is 254 (normal values 180-914 pg/mL at this lab).
How much methylcobalamin should she start to take per day? We are afraid to put her on a B complex because of the small fiber (her B6 levels were non-toxic but the neurologist said B6 was fine and he didn't think she should be on a B-complex supplement). She is currently taking benfotiamine as a result of my readings on these boards.

Thanks so much.
