The treatment methods for acute mastitis start with stopping breastfeeding. For those with mild symptoms or less severe conditions, breastfeeding can continue, but it is not advisable to breastfeed from the affected breast. Instead, a breast pump can be used to express the milk. Secondly, the breast can be supported with a bra. Thirdly, for local redness and swelling, hot compresses can be applied, or ichthyol ointment can be used topically, as well as Levonorgestrel topical application. If blood tests show elevated levels, systemic antibiotics should be used, with the choice of penicillins and cephalosporins for symptomatic treatment. If an ultrasound shows an abscess formation, it is recommended to perform an abscess incision and drainage procedure, or, if it's deeper, a thick needle can be used for aspiration to draw out the abscess.
