There are also lymph nodes on the face. Generally, there are lymph nodes on the surface of the body, often accompanied by the distribution of the venous system, because the lymph nodes on the face are relatively small, and the fat on the face is thicker, so the lymph nodes can not be felt in general. However, if there is inflammation in the mouth or in the face, it can lead to swelling of local lymph nodes and pain, and at this time, the lymph nodes can usually be touched, and if necessary, ultrasound examination can also find inflammation and swelling of lymph nodes. Oral antibiotic treatment, generally after 7-10 days of treatment, the inflammation of lymph nodes can subside, and the primary lesions inside the mouth can also be relieved.
