I have small fiber neuropathy and autonomic neuropathy from SFN, so I can relate to what you are experiencing...however my causes are different.
Welcome to our forum. We have some very nice, knowledgeable, supportive and funny folks in here. At times it reminds me of the old show, "Cheers" or maybe the more recent, 'Friends'...I don't know...some of us are long timers, and some are new...but all are welcome.
