Usually, when the milk is swollen to the point of obvious swelling and pain during the period of breastfeeding, some of the milk can be discharged in order to alleviate the symptoms of discomfort and prevent mammary gland diseases. During the period of returning to the breast, you can use a breast pump to discharge part of the milk from the breast when you feel the obvious swelling and pain in the breast, so as to reduce the swelling and pain in the breast area and prevent the occurrence of mastitis. It is worth noting that you should not overuse the breast pump to get rid of all the milk in the breast, so as not to stimulate the breast to continue to produce milk and increase the degree of swelling. The woman should pay attention to breast care, try to wear loose, pure cotton underwear, to avoid foreign body friction stimulation of the breast. Mothers should also pay attention to the rationality of the diet, to ensure a balanced intake of nutrients, but should avoid spicy and stimulating food, so as not to increase the amount of milk secretion. If breast swelling and pain persists or accompanied by fever and other symptoms during the refeeding period, it is necessary to be vigilant against breast diseases, and mothers are advised to seek medical treatment as soon as possible.
