For a few years now, most times
when I stand up in over 22-5 degree Celsius
heat ish, my feet start to go red and itchy after 5-10 minutes? It's always the top of my feet and a red, flat, itchy rash occurs. This can often also occur under my knees and is almost mottled looking. Sometimes in extreme heat, such as hot showers, I can get the rash all the way up my legs and even on my chest, however these areas do not tend to be as itchy.
