I'm wondering why are my breasts sore?

Breast Pain: Cyclic changes in hormone levels are the most common cause of breast pain (prior to menopause). When this "flies above the radar", we give it fancy names like "mastalgia" and "fibrocystic changes". Some women respond to caffeine avoidance, vitamin e, oil of primrose, or even occasional nsaids. Please discuss your concerns with your gynecologist--they should be able to reassure you not to worry.

Not sure: Causes of breast pain can include cysts, prior surgery, trauma, medications (oral contraceptives, infertility tx, ssri's), large breast size, premenstrual syndrome, ovulation, period ; pregnancy. Your physician may be able to help determine the cause.
