Mastitis

Mastitis is inflammation of the breast, most commonly due to infection. Mastitis usually occurs in breastfeeding women if milk ducts are blocked, and milk cannot flow out. Bacteria can enter through a duct opening or a crack in the skin of the nipple, and multiply in the milk. Symptoms of mastitis include breast pain, swelling, warmth, and redness.
