Necrotizing cervical lymphadenitis can lead to the consequences of decreased immunity and resistance in the patient afterwards. Patients with necrotizing cervical lymphadenitis can experience certain sequelae after healing, especially a decrease in their own resistance and immunity, because the lymph node is one of the most important immune organs in the human body, and it contains a large number of lymphocytes, which are directly involved in the body’s immune response. Through cellular immunity the pathogenic bacteria that invade the human body can be effectively killed. Therefore, necrotizing cervical lymphadenitis can lead to a decrease in immunity, and patients can experience neck pain, accompanied by a series of abnormal manifestations such as increased body temperature. It is recommended that the patient go to the general surgery department of the local hospital and listen to the advice of a professional doctor.
