Breast engorgement which may manifest swell, throb, and cause mild to extreme pain is the common difficulty for breast feeding woman. It occurs in the mammary glands due to expansion and pressure exerted by the synthesis and storage of breast milk and it usually happens when the breasts switch from colostrums to mature milk. However, engorgement can also happen if lactating women miss several nursing and not enough milk is expressed from the breasts. It can be exacerbated by insufficient breastfeeding and/or blocked milk ducts. Engorgement may lead to mastitis and untreated engorgement puts pressure on the milk ducts, often causing a plugged duct.
