With PN, or small fiber neuropathy, prognosis MAY depend on what is the underlying reason for the SFN to begin with. Often they try to find out if it is the result of some disease. If it is idiopathic, prognosis is more difficult to predict....on the other hand, all neuropathy is difficult to predict.

Once you get the test results you will have more direction.

Waiting is hard, and it is always as shock to get the diagnosis.
