For skin ulcers, the first thing you need to do is to check the blood count to see if there are elevated white blood cells to determine if there is a bacterial infection that has been caused by this. If the white blood cells are elevated, anti-infective treatment can be given orally with antibiotics such as roxithromycin or azithromycin or cefradine. At the same time, saline rinses can be used to clean the wound, and external application of ezacridine lactate solution or skin health solution can be done after 1:5 dilution of wet compresses, twice a day, for 20 minutes at a time. Comfrey oil can be used topically to remove decay and regenerate the muscle, and anti-inflammatory ointments such as fusidic acid ointment or clindamycin phosphate gel or mupirocin ointment can also be used. Keep the wound clean to avoid covering it with dirt causing contamination and aggravating the infection.
