Patient's question:
Pain. It comes and goes. Sometimes it doesn't hurt.Doctor's answer:
Lymph nodes are important immune organs in the human body. A normal person has about 500-600 lymph nodes, which can be divided into superficial lymph nodes and deep lymph nodes based on their location. In clinical practice, the lymph nodes primarily examined are superficial lymph nodes, as deep lymph nodes often show no symptoms in the early stages of enlargement.
