My 4 year old daughter got a rash on the skin surrounding her mouth that appeared as dry crusty red skin at first. It continued to get worse over the next two days. Now she has raised bumps on her knees, elbows, tops of feet, behind the ear, on her neck, and backs of hands. They are itchy. The rash on her face has gotten larger and darker red, with possible oozing. She was feeling fine, but now has a low fever.
