I received the lidoderm patches today, so anxious to give them a try. I'll try different locations MrsD suggested over the next few days.

I had a skin biopsy almost 3 years ago at Hopkins. There were some mild changes in the fibers themselves, but nothing consistent enough with SFN. I wonder if I should consider repeating the test with increased pain in my feet, and now the new allodynia in both lower legs?

Glenn, isn't the allodynia consistent with SFN? If so, then the skin biopsy should pick it up this time, right?
