Lymph nodes are small, bean-shaped parts of the body. They help your body fight germs and infections.
You can find lymph nodes in many places, like the neck, armpits, and groin. When your body is fighting sickness, they can swell and feel tender. Doctors may check them during an exam to learn about your health.
