Mastitis is an inflammation of the breast that occurs most commonly in breast-feeding women; it can be related to tissue injury, infection, or both. Breast-feeding mastitis is typically caused by bacteria that enter the breast through a cracked or sore nipple.
Signs of infection may include:
- Increased pain, swelling, redness, or warmth in an area on a breast.
- Red streaks extending from a breast.
- Drainage of pus coming from a breast.
- Swollen lymph nodes in the neck or armpit.
- Flu-like symptoms, such as fever of 100° (37.8°) or higher, chills, and fatigue.
Treatment usually involves antibiotic medicines, keeping up milk flow, and measures to relieve discomfort. While they are being treated, most women can safely continue to breast-feed or pump breast milk.
