Breast pain

Breast pain (also known as breast tenderness, mastodynia, mammalgia, and mastalgia from the Greek μαστός mastos, "breast" and ἄλγος algos, "pain") is a medical symptom. Pain and discomfort may range from minor to severely incapacitating. Breast pain during lactation or after weaning is not included into this definition but is usually classified as breast engorgement or mastitis.
