I've never had a biopsy, so I really cannot advise you.
Some others may come on here. I believe however that all
it will show is that you have axonal damage. This is not really
going to say WHAT is damaging you however.
I'd Google some more. It had been my impression that this sural
biopsy is not done much anymore.
Maybe Glenn will come on with more information. He has had
the skin punch biopsies more than once.
