If you have a fever, you need to stop nursing your child immediately, then use a breast pump to suck the breast milk out of your breasts and apply a hot towel for warm compresses. If your breasts become red, swollen, hot or painful, you need to go to the hospital for antibiotic injections. To prevent inflammatory infections or sepsis, selective antibiotics and, if necessary, intravenous antibiotic drips are needed based on the results of bacterial culture and drug sensitivity tests. If the milk increase cannot be relieved, surgical incision and drainage is required. If surgical incision and drainage is indeed required, breastfeeding must be terminated for the child and milk return medication must be used. If the temperature exceeds 38.5 degrees, you need to take antipyretic medicine to reduce fever, you can take ibuprofen suspension.
