Lymphatic infection is a relatively common clinical condition, which is well-treated and overall not considered serious. Lymphatic infection occurs mainly due to inflammatory lesions in the surrounding organ system, resulting in reactive enlargement of lymph nodes in the nearby area, accompanied by lymph node pain, which is the manifestation of lymphatic infection. The treatment effect of lymphatic infection is relatively good, the treatment method is mainly anti-infective treatment and application of antibiotics, the common antibiotics are cephalosporin antibiotics, at the same time for the primary infection foci of the etiological treatment, after systematic treatment, the infection will subside, the lymph nodes will shrink, the pain caused by infection will disappear. For patients who are clinically suspected of lymphatic infection, if the effect of anti-infection treatment is not good and the lymph node enlargement does not disappear, we need to be alert to the possibility of tumor and tuberculosis lesions.
