Erythema marginatum in toddler
My 2 year old daughter has developed a strange rash on her torso, and face. We had her tested for allergies yesterday and nothing came back positive so its not allergies. The rash includes erythema marginatum which are circular/oval red rash that is white in the center. Other parts of the rash are just red areas. They blanch when pushed. They are slightly itchy, particularly when she is warm. She had a fever on and off three weeks ago. She has had a low fever (99) on and off this week. She also has been saying her stomach hurts on and off for about a week & she was constipated too. Other than that, she seems fine. She's happy to play and acts normally. The dr sent us for blood work to rule out rheumatic fever. We are waiting to get results back. Could it be anything else?
