i have no way of "seeing" this rash over the internet but my concern would be that the cat scratch has caused a skin infection that may require oral antibiotics. cat scratches are notorious for causing skin infections incidentally.
skin infection and rash after cat scratch on leg. very painful and itchy. rash is small raised red bumps that peel. tenderness is present. the rash is not symmetrical around wound but more fan shaped. after two days infection has lessened less redness and heat. rash is persistent but has stopped spreading. what is this rash?
