I am posting for a friend who's upset I'm not taking her seriously.
She reports getting itchy feet and lower legs when walking on a wet surface. It doesn't matter what shoes/socks/trousers are worn, and the itchiness disappears after a few minutes of standing still. No rash or anything to see and it doesn't happen in the shower. It has to be a wet outside surface, and the itchiness is worse if the surface is dirty.
She's as mad as a box of frogs, right?!
