What’s wrong with the swollen lymph nodes under the forehead that don’t go away?

There is no subfrontal lymph node, but the subfrontal lymph node may refer to the subchin lymph node, which is the lymph node under the chin and chin, or it may be the submandibular lymph node, which is the lymph node under the jaw bone. If the swollen lymph nodes under the chin or under the jaw do not subside, it is possible that the inflammation in the mouth and face does not subside, which causes the lymph nodes in these areas not to subside, but it is also possible that the swollen lymph nodes are caused by malignant diseases, such as tumors in the mouth or tumors of the lymphatic system, such as lymphoma. If this happens, you should go to the hospital promptly.
