Hi Craig, I’ve had SFN for a couple of years and just began experiencing the discoloration in my arms-mostly freckles of all sizes and some light pink spots plus a slight burning. This starts after I wake in the morning. I have also noticed that I am losing more hair than usual. I’ve started taking vit. E and biotin to see if that helps. It seems that there are a crazy amount of symptoms associated with this disease and no good explanation for its cause. Are you taking any meds or supplements presently? Helen
