I am 29. I have had a rash on my areola for the last 3 months. It seems I have taken everything known to man for it, including antibiotics and a steriod cream. I went back to the dermatologist yesterday for a follow up, and they did a punch biopsy b/c it still had not cleared up. The doctor also made a comment that the skin had already started thickening up. What is this suppose to mean? I am very nervous right and not sure what to think. Could this be a sign of something serious?
