Butt boils may heal on their own, depending on the size of the boil, the extent of the lesion and on a case-by-case basis. A boil is an acute purulent inflammation of the deeper parts of the hair follicle and surrounding tissues, often caused by Staphylococcus aureus infection. If the boils are small in size and present as sporadic follicular inflammatory papules, the boils may heal on their own as they mature from hard nodules to yellowish-white punctate pus plugs, which are dislodged, and the inflammation subsides as the pus and blood and necrotic tissues are drained. If the boils are numerous and recurring, they need to be treated accordingly. In the early stages when the boils are not suppurating, topical application of 20% ichthyol ointment, mupirocin ointment, etc. may be an option. When local treatment is ineffective, antibiotics such as cefaclor and amoxicillin can be taken orally according to the drug sensitivity test. If the fusion forms a carbuncle, surgical incision is required to exclude and drain the pus, and regular medication changes are required for treatment. When boils appear on the buttocks, you should pay attention to skin cleanliness, prevent trauma, and improve the body’s immunity. Please do not self-medicate, it is recommended to go to the hospital for diagnosis and treatment under the guidance of a doctor.
