Lymph nodes are normally present in the body and are an important part of the body’s immune system, and it is impossible to eliminate them. When lymph nodes become swollen, they can be treated by means of therapy, i.e., they can be reduced rather than eliminated. Most of the swollen lymph nodes are caused by local infection, and the swelling is temporary and related to the stimulation of infection, so active anti-infection treatment is needed for the infection, for example, cephalosporin antibiotics can be chosen to regulate anti-infection, and the swollen lymph nodes will subside after the infection is effectively controlled. If the swollen lymph nodes are caused by tuberculosis, standard anti-TB treatment, such as isoniazid and rifampicin, can be used.
