If these changes you have been experiencing are only on that one side, or in that one breast, I would take your symptoms very seriously and go to a doctor. I understand about the insurance and don't know how to take this into consideration, but check if maybe there are possibilities for low, or no cost, exams. I mean, I know there are but I would not be able to tell you how to go about finding them. Best, Kat
Dear hillbilly01: Without evaluation, including clinical breast examination (and likely mammogram and/or ultrasound) it is impossible to speculate on what this might be. Skin on the breast is like skin anywhere else on the body and is subject to a variety of abnormalities. The only way to sort through both the lump and the rash is to have it evaluated by a doctor.
