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. This only ever occurs when standing up statically, if I walk the symptoms diminish. An aching sensation in my knees can often occur as well. This usually does not occur too often as I live in the U.K.
