Blocked milk duct


A blocked milk duct is a blockage of one or more ducts carrying milk to the nipple for the purpose of breastfeeding an infant. The symptoms are a tender, localised lump in one breast, with redness in the skin over the lump. The cause of a blocked milk duct is the failure to remove milk from part of the breast.
