I have had this rash on and off for the last few months. As of yesterday it will not go away. It is all over my cheeks and chin and nose and some on my forehead. It's not really itchy. I have taken allergy medicine and Benadryl but it hasn't helped. It isn't really like hives. Almost looks like acne but the bumps are all the same size and they're just red no white heads or anything. You can't really even feel them. It's almost as if they're under the skin. Please help.
