Red and hard pimples without pus may be early symptoms of boils, which can be treated by observation, medication and surgery. 1. Observation: In the early stage of boils, the main symptom is an inflammatory papule protruding from the skin and forming a hard nodule with redness and swelling. As the disease progresses for several days, the center of the boil will become soft and fluctuating, and the pus plugs will be dislodged, and most of the boils will heal on their own. 2. Medication: Topical antibiotic ointment, such as erythromycin ointment and mupirocin ointment, can also be used. 3. Surgery: For patients who have a lot of pus that can’t be easily discharged or who have repeated episodes of pus, surgery can be performed to incise and drain the pus. It is recommended to go to the hospital for examination and decide the specific treatment measures under the guidance of the doctor.
