Periumbilical lymphadenitis in children is mainly caused by upper respiratory tract infection (pharyngitis, laryngitis and rhinitis). It is suggested to keep warm, enhance physical fitness and prevent colds from getting angry. Don't eat irritating food, such as pepper and garlic, and don't eat too cold fruits and cold drinks. It is recommended to heat before eating. Toona sinensis and seafood had better not be eaten recently.
If the upper respiratory tract infection is serious, you can take some antibiotics and anti-inflammatory drugs orally, but not for more than three days, with great side effects; Lymphatic plaster can be combined with oral Chinese patent medicines such as Prunella vulgaris ointment and forsythia Baidu pill.
If you answer attentively, I hope to adopt it.
