Let’s start with some postpartum breast care issues. After childbirth, lactogen levels rise (especially in natural births, which are favored because of the pain and other stimuli to release lactogen during delivery) and breast tissue lactates. At first, lactation is very small, but as the baby sucks and needs increase, lactation generally increases with it. However, at the beginning, because the milk ducts at all levels of the breast have not yet expanded, there is little milk stored, which is reflected in the small amount of milk discharge, the baby does not eat enough, and the nipples often overflow, so it is necessary to massage the breast and rub open the “hard knots” in the breast. Massage requires patience, persistence over many days, and avoiding violence. During breastfeeding, pay attention to washing the nipples and breasts every day, keep them clean, wipe them with a softer towel; try to let the baby empty one side before eating the other when feeding, and try to empty the milk every day. Do not let the child sleep with the nipple or use it often to coax the child. There are two conditions for mastitis to occur: one is milk accumulation and the other is bacterial invasion. Bacterial invasion is often due to a small slope fissure in the nipple skin. For your case it is recommended to: 1. suspend breastfeeding, when mastitis is suspected the affected side should stop breastfeeding to avoid cross-infection with infants; 2. empty the milk, keep the nipples and breasts clean; when using a breast pump you can massage the breast while sucking; 3. you can use some herbs externally to promote inflammation limitation and clear heat and detoxification; 4. anti-inflammatory treatment; 5. it is recommended to review the breast ultrasound and see a doctor to except if there is If there is an abscess in the breast, surgery is needed to drain the abscess. Generally speaking, acute mastitis can be cured, a few can be transformed into chronic inflammation.
