This is a good question. It is important for you to make an appointment with your primary care doctor
or OBGYN to have a full physical and examination and determine the cause of your symptoms and obtain appropriate treatment. Depending on what your doctor finds during your visit, he or she may order further testing or refer you to a dermatologist
. From your symptoms it is possible that you are having an allergic reaction to something that your breasts came in contact with, such as a new bra or pajamas. Also consider whether you have recently switched laundry detergent, soap, or lotion that could be causing your skin to react. Another possibility is hormonal changes, such as during PMS (premenstrual syndrome) or pregnancy, so if there is any chance you could be pregnant you need to be tested right away. Although extremely rare, certain types of breast cancer (Paget's and inflammatory breast cancer) can present with these skin changes so, again, it is very important for you to see your doctor as soon as possible especially if you have a family history of breast cancer. In the meantime, wear loose cotton clothing and take quick lukewarm showers to avoid exacerbating your symptoms.
