Hi @alladria, welcome to Mayo Clinic Connect. I have idiopathic small fiber peripheral neuropathy. I have no medical training or background but do believe that it's possible for a pinched nerve to be the cause of small fiber neuropathy. Here's some information about nerve damage that discusses the subject a little.
