Around 1 in 5 breastfeeding mums get mastitis, a painful infection of the breast tissue usually caused by a blocked milk duct. 
Sore, cracked, or bleeding nipples affects around 50% of breastfeeding people in the first week after birth. Engorgement can also lead to dry and irritated skin.
When the breast tissue overfills with milk, blood, and other fluids, it can make your breasts feel full, swollen, hard, or painful.
