It is normal to feel lymph nodes on both sides of the chin when you bow your head, but it may also be caused by diseases (e.g. lymph node infection, lymphoma, etc.). There are superficial lymph nodes in the chin area, which are normal lymphatic tissues in the human body. As these lymph nodes are in the superficial layer of the skin, they may be easily touched when bowing down, which is a normal phenomenon, and are usually not accompanied by pressure and pain, swelling, etc. Moreover, the lymph nodes are softer, and are usually more movable. Lymph nodes felt on both sides of the chin may also be due to lymph node infection, lymphoma and other lymph node enlargement. Diseases such as leukemia and systemic lupus erythematosus may also cause swollen lymph nodes in the neck. Disease-induced lymph node enlargement is usually accompanied by obvious pressure and pain, and obvious lymph node enlargement. When you find swollen lymph nodes accompanied by pressure and pain and other symptoms, you should go to the hospital for examination and treatment in a timely manner to avoid delaying the condition.
