Erysipelas belongs to capillary lymphangitis, mainly caused by infection with hemolytic streptococcus. It mainly presents as pain in the lower leg and the appearance of red streaks on the lower leg, which can be accompanied by local swelling. If left untreated, it can potentially lead to sepsis. Once erysipelas is diagnosed, if medication is recommended, anti-inflammatory drugs such as penicillin can be taken. It is best to treat with intravenous penicillin for more than 7 days. After the symptoms of erysipelas have completely disappeared, it is advisable to continue using the medication for about 3 days, after which medication can be stopped. During the treatment period, it is necessary to avoid alcohol and refrain from consuming spicy and stimulating foods. (Please use medication under the guidance of a doctor, and do not self-medicate blindly.)
