For breast pain caused by mastitis during milk engorgement, we can use hot compresses and massage to fully expel the milk. Locally, a 25% magnesium sulfate poultice can be applied for 20 minutes, three times a day. After breastfeeding, cold compresses can be used to reduce the pain caused by milk engorgement. In cases of mastitis, it is important to keep the nipple clean, frequently washing with soap and warm water. Before and after breastfeeding, the nipples can also be washed with 3% boric acid solution. For inverted nipples, gently squeeze out the nipple before cleaning. However, it is not advisable to wipe with ethanol, as ethanol can make the skin of the nipple and areola brittle, leading to fissures. Develop good breastfeeding habits, feed at regular intervals, ensure the milk is fully drawn each time, and if not, manually express or use a breast pump to remove the milk.
