Dear Shelleyfish79: Skin on the breast and areola is like skin anywhere else on the body and is subject to a variety of abnormalities including pimples. It is also possible that you have identified a little sebaceous gland which secrete a whitish oil and are a normal part of breast anatomy. If this becomes worse, you can have your doctor take a look. Regarding the breast pain, it is not at all uncommon for women to experience breast pain mid menstrual cycle that resolves with the menstrual cycle. Certainly, hormones can contribute to breast pain.
