Answer:
Among the range of uncomfortable symptoms, swollen lymph nodes tend to spark feelings of dread. They can become quite large, feel tender to the touch, and signal a wide variety of illnesses, from common infections to more serious conditions. But having a swollen lymph node isn’t always a big deal. It’s usually a good sign: These tender glands—most prominently in your neck, groin, and armpits—are showing that your immune system is in a battle to keep your body healthy. The vessels of the system are like a highway of one-way lanes; lymphatic fluid that’s full of immune cells is pushed throughout your body, according to the Cleveland Clinic. Along the way, the fluid passes through these bean-shaped (about 600 of them!), which are located in clusters, from your knees up to behind your ears. These nodes, which are the size of a pea, are filled with more disease-fighting cells. While the lymphatic fluid is on the move, the immune cells scan for “bad guys”—say, a virus or a bacterium—and if it comes across them, it triggers the nodes to boost the number of their disease-fighting cells. This causes swelling to fight off the infection, “and when the job is done they return to their normal size. Swollen lymph nodes are temporary and will eventually resolve on their own. But how can you tell if these enlarged glands are a sign of something more serious? Here’s how to identify swollen lymph nodes, what causes them, and when the symptom actually warrants a visit to your doctor’s office. Normally, lymph nodes aren’t visible, but when they’re swollen you may (or may not) be able to see a bump. Depending on how enlarged they are, swollen lymph nodes may feel like little rubbery nodules the size of a pea, or as big as a cherry or even a plum (either soft and tender or firm).

Lymph nodes often swell in one location when a problem such as an injury, infection, or tumor develops in or near the lymph node. Which lymph nodes are swollen can help identify the problem. The glands on either side of the neck, under the jaw, or behind the ears commonly swell when you have a cold or sore throat
