I have never asked this question before,what is the difference between non length dependent small fiber neuropathy and length dependent SFN? Do they cause the same types of symptoms and problems? Or how do they vary? If someone could answer that question in laymen terms I would appreciate it. If it gets to technical I have a hard time holding on. I was told that since my SFPN was full body, that I have a non length dependent type. Thanks for any responses.
