Lymphadenitis of the neck in children has the potential to heal on its own, but how long it takes to heal on its own depends on the patient’s own resistance and the severity of the condition. Pediatric cervical lymphadenitis is mainly manifested as a lump in the neck visible to the naked eye, with a smooth surface that can be pushed, and localized pressure pain or slightly elevated skin temperature. If the symptoms are mild and there is no other physical discomfort, and if the body is resistant, no special treatment is needed, and it usually heals itself in 7-15. However, if it is accompanied by recurrent fever, poor mental health, low appetite and other systemic symptoms, it is necessary to promptly go to the pediatric department of the hospital for examination and give symptomatic treatment after clear diagnosis. The child can choose broad-spectrum cephalosporin intravenous input treatment to control the infection, and the condition will usually gradually improve in about 1 week. During the treatment period, children should pay attention to drink more water and eat more fresh fruits and vegetables to ensure the daily caloric intake, and cooperate with local hot compresses to improve the blood microcirculation of the neck.
