Engorgement is a normal physiological condition that usually occurs in the first week of breastfeeding when the mother’s milk comes in. Engorgement can be associated with significant discomfort or pain for some women. Increased fluids, inflammation and milk all contribute to engorgement.
Breasts may feel heavy, hard, possibly lumpy and warm to the touch. The mother may have a slightly elevated temperature (99°-100° F; 37.2°-37.8° C). The skin is stretched, and nipples may flatten. Getting the baby latched on can be difficult or impossible in some cases.
