Hi I have been diagnosed with small fiber neuropathy also. Went to Lahey clinic and Mass General. I got the feeling that because the doctors can not exactly explain how or why I have this condition that some how its either my fault or I am making it up they are dismissive of me. Anyway I am taking 1200mg a day of gabapentin and duloxetine x3 a day, but my best relief comes from lorazepam and asper cream and lidocaine applied very liberally during all day. I also use a tens some times but it is a pain . Do not give up some where some time someone will figure it all out ,or some doctor will stumble on a fix by accident. Stay strong .Watch a good movie, read a good book, watch some old tv shows on YouTube. Distracting my self from the burning scrapping digging pain is a big part of my learning to live with this privation to my health. Good luck to all and GOD bless
