Strange Rash On Legs-Paging Dr. H&F

[sadlebred]

DH and I have been doing a TON of walking each day for the last 3 days, up to 10 miles. This is much, much more than I ever do. The first day I noticed a rash on the lower parts of both of my calves. It's red and splotchy but not raised. It doesn't itch, doesn't hurt, isn't bugging me. It's just a rash. Has anyone seen anything like it? I thought at first it might be related to the heat, but that doesn't seem to be the case.

Obviously, if it changes, gets worse, or starts bug me, I'll go see the PA at my dermatologists's office.
