Boils on the breast are treated in the same way as boils on other parts of the skin. If the boil has just formed in the early stage and there is no obvious formation of pus, you can apply topical antibiotic creams, such as fusidic acid cream or erythromycin ointment. Physical therapy, such as red light therapy, can also be performed to promote the absorption of inflammation. If a certain amount of pus has formed, the corresponding treatment is carried out according to the severity of pus formation. If the pus formation is not obvious, you can temporarily apply topical Longzhu ointment or use topical application of ichthyolite ointment. If the pus formation is more obvious and there is a fluctuating feeling, incision and drainage are needed. After the incision and drainage of pus, it can promote the absorption of local inflammation and prevent the formation of pus cavities, which can eventually lead to large-scale mastitis. In addition, oral antibiotic treatment, such as oral roxithromycin, is also needed.
