Why does it hurt when I pump?
Some mothers feel pain in their nipples and areolas while pumping. It’s important to find the cause, because pain is unpleasant and it can make expressing less effective, resulting in a decreasing milk supply and other problems. Mothers who have pain should try to find which area is painful. This can help find the cause. Mothers may need to try different sizes and styles of breast pump shields and make sure the shield is centred on the nipple before and during pumping. If the pain is because the suction is too strong, mothers may need to decrease the suction and consider improving the let-down, breast compression, manual expression, or using a constant-suction pump. Sometimes the pain is because the pumping time is too long. Mothers should reassess their technique if it takes more than 20 minutes on each breast.
