The appearance of hard lumps in fire boils is mainly due to the infection of Staphylococcus aureus, which can be treated with medication or surgery. 1. Drug treatment: if the fire boil has hard lumps and has not yet suppurated, ichthyol ointment and mupirocin ointment can be used to apply, and for those who have large lesions or recurrent episodes, and the local treatment is ineffective, antibiotics such as enzyme-resistant penicillin and cephalosporin can be taken orally. 2. Surgical treatment: for those who have been pus and have not broken through, incision and drainage should be considered in aseptic conditions, so that the pus can be discharged. Patients should pay attention to skin cleanliness, avoid scratching leading to rupture, enhance the body’s immunity, treatment under the guidance of the doctor, and actively search for the underlying disease or causative factors, pay attention to personal hygiene in daily life, avoid staying up all night, and pay attention to rest.
