Hi, I started having a itch rash on knees and elbows kind of a few heat spots that was very itchy. This was 2 weeks ago and has know on my arms legs belly and penis head as we'll as my back. The rash ain't intense but spread out. Went walk in centre and they just advised it's dermatitis but obviously isn't. I also have a 1 or 2 of these heat spots on feet and hands.
