If an abscess is found in the breast during breastfeeding, it should be treated promptly in a hospital, with the option of surgery for incision and drainage. Preoperative ultrasound examination of the breast should also be performed, as well as local puncture to clarify the location and depth of the abscess cavity, either by making an incision at the lower edge of the breast or by performing counter-oral drainage. The main purpose is to drain the breast adequately to avoid residue, and to change the dressing regularly after surgery. If the gauze is found to be soaked with pus or with bloody exudate, it should be changed promptly. While changing the medication, it is also necessary to actively cooperate with intravenous anti-infection treatment, which can choose inexpensive penicillin sodium for intravenous input, or erythromycin can be applied. And during the breastfeeding period, you should also pay attention to the affected breast to stop breastfeeding, the use of all the drugs for infants or less side effects, but also pay attention to the regular review of laboratory tests.
