Erysipelas is mainly caused by a bacterial infection of the lymphatic system, resulting in lymphangitis, primarily affecting the superficial lymphatics of the skin's dermis. The common pathogen is Group A hemolytic streptococcus. For erysipelas, proactive anti-infection treatment is necessary, typically opting for penicillin-class antibiotics. For patients allergic to penicillin, other types of antibiotics such as cephalosporins or macrolide antibiotics can be considered. If there is significant local swelling and pain, magnesium sulfate can be used for local wet compresses to reduce swelling and alleviate pain. Additionally, traditional Chinese medicine treatments can be considered, such as taking oral medications that clear heat and detoxify.
