Aussie,

I agree with LizaJane's question about the skin biopsy if the diagnosis has been made. It's too bad they didn't replace the technician because someone does physically count the nerve fibers after they have been stained for clarity. Are they considering the skin punch biopsy as a way to monitor the progression or improvement in your SFPN? I've read that this can be done and is a great advantage of the skin punch biopsy.

I do hope an alternate beta-blocker will help you sleep.
