--what is meant by a "skin distrubance"?

Obviously, there are a lot of skin conditions that can produce all sorts of unusual sensory sensation by affecting the nerves, but these don't start in the nerves, and are different from, say, a small-fiber neuropathy that produces numbness or parastheses (disturbed sensations) through direct damage to the nerves.

Do you have any evident rash, or discoloration?
