A boil that keeps running pus requires further surgery and treatment with antibiotics to obtain a cure. A boil with pus indicates a bacterial infection, which requires routine disinfection, retention of some of the pus for bacterial culture and drug sensitivity testing. The abscess is then incised to reach the bottom of the abscess cavity to see that all the pus is drained, and the inactivated tissue is removed and the dressing is changed intensively. The most common bacteria that appear as pus in a boil bacterial infection is Staphylococcus aureus, so you can use empirical medication and choose a generation of cephalosporins or penicillins, which can be taken orally. In severe cases, that is, when the boil is relatively large, or when symptoms of chills and fever appear, intravenous antibiotics can be considered, followed by intensive drug changes, and the use of antibiotics needs to be adjusted if necessary according to the results of bacteria and drug sensitivity cultures.
