The hard lumps of boils can sometimes subside on their own, mainly in people who are physically strong and have a relatively high immune system with strong resistance to disease, which can lead to the aggregation of repellent inflammatory factors around the hard lumps of boils for treatment. However, if the hard lumps of boils are large in extent or number and are accompanied by severe pain, they often do not subside on their own at this time and require antibacterial treatment for intervention, which can be done by intravenous clindamycin phosphate injection or levofloxacin hydrochloride injection. If there is redness and swelling you can apply a local cold wet application of Esaacridine Lactate solution, followed by an application of Ofloxacin gel or Erythromycin ointment for antibacterial and anti-inflammatory treatment.
