Thank you everyone Nope...I'm not taking supplements, but I'm sure I need to. Ken in Texas, I wonder if it could be a flare, but I'm sure I've never, in 15 years, been in this much pain. It's been horrible. The problem is...I have a small children and I work full-time and my husband has been taking on way too much. Going to call another neuro who was recommended to me by a friend. Hoping for some answers. Still not convinced I have SFN b/c of the negative punch biopsy. We'll see. Thanks again...I appreciate everyone taking time to respond and help me out.
