Sorry you have SFN, but you can join the club here! Bad news, good news?? At least you have a diagnosis of it now and can proceed from here. I was kind of relieved in a way to get the diagnosis. Shocked but relieved, if that makes sense.

Sounds like they are testing you for hereditary neuropathy. I think Kitt will give you more info. She is familiar with Athena testing.

Also sounds like your doc knows what he is doing!
