The most commonly used treatment method for erysipelas infection is penicillin (to be used under the guidance of a doctor). If the patient is not allergic to penicillin, it can be administered intravenously for significant effects. However, it is important to ensure that the treatment duration is sufficient, generally requiring medication for two weeks for better outcomes and to reduce recurrence, given that erysipelas is highly prone to recurrence. If the patient is allergic to penicillin, it is recommended to use alternative antibiotics such as clindamycin (to be used under the guidance of a doctor). Additionally, patients should minimize walking and elevate the affected limb during treatment.
