For about 18 months now, since my SFN worsened, ive noticed changes in my nails. My toenails have Beau's lines, horizontal ridges which make my large toenails look the surface of shells. My finger nails have the appearance of Terry's nails. A dermaologist was dismissive of this but I know what I know and see these changes with my own eyes! My GP blamed medication ive been on but I haven't been on any drugs for Rheumatoid Arthritis for 8 months now.

I wonder if small fiber neuropathy can affect the nails in this way because of changes in the small nerve fibers of the skin - anyone else find this?
