Lymph nodes are small, bean-shaped glands throughout the body. They help the body fight germs and infections.
Many things can cause the lymph nodes to swell. In most cases, swollen lymph nodes are not serious. Sometimes lymph nodes can swell when there is an infection in the area. For example, the lymph nodes in the neck, under the chin, or behind the ears may swell and hurt a little when your child has a cold or sore throat. And an injury or infection in a leg or foot can make the lymph nodes in your child's groin swell.
Treatment depends on what caused your child's lymph nodes to swell. In most cases, the lymph nodes return to normal size on their own after the cause is gone. It may take a few weeks before the swelling goes away. If the swollen lymph nodes are caused by an infection, your doctor may prescribe antibiotics.
Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.
