Lymph nodes that do not subside may be caused by the cause of the swollen lymph nodes that have not been eliminated, and localized swollen and painful symptoms exist, most commonly in the cervical lymph nodes, usually due to acute or chronic pharyngitis. Acute pharyngitis is persistent, inflammation exists, or chronic pharyngitis is localized in people who talk a lot, which may lead to long-term enlargement of lymph nodes in the lower jaw or neck. If the lymph nodes are enlarged due to tuberculosis or malignant tumor, the local lymph nodes will not disappear if the local tuberculosis or malignant tumor has not been detected or even treated properly. Physiological factors, such as relatively thin people, can feel their lymph nodes, and if there is no obvious local swelling and pressure pain, generally not caused by other diseases, do not care too much, and do not need special treatment.
