Inflammation of the lymph nodes in the neck is usually caused by bacterial or viral infection, which is treated with antibiotics or antiviral drugs, and in a few cases, incision and drainage are needed. 1. Respiratory tract or lung infections, such as lobar pneumonia, bronchopneumonia, tuberculosis, etc., can cause cervical lymph node inflammation. After chest CT examination, bacterial culture and drug sensitivity test, antibiotics, anti-viral drugs, anti-tuberculosis drugs (isoniazid, rifampicin, etc.) should be used to treat the symptoms in time and according to the doctor’s prescription. 2. Inflammation of the oral cavity and throat, such as gingivitis, pharyngolaryngitis, oral anti-inflammation, etc., can also lead to inflammation of the cervical lymph nodes, which should be treated symptomatically according to the etiology. If combined with purulent lesions of local tissues, abscess incision and drainage is often required. It should be noted that when there is a situation in which the lymph nodes in the neck have been inflamed, it is necessary to go to the hospital in time, under the guidance of the doctor for examination and treatment.
