This document discusses breast engorgement, which occurs when milk production causes swelling and hardness in the breasts. The key causes are when milk "comes in" a few days after birth or if feedings are missed. Symptoms include pain, swelling, redness, and difficulty latching. Treatment involves frequent feeding or pumping to remove milk, applying hot or cold compresses, and using supportive bras. Medications like proteolytic enzymes or bromocripine may also help in severe cases. Preventing engorgement requires early and frequent breastfeeding on demand.
