Patient education: Swollen neck nodes in children (The Basics)

What are "nodes"? — 

Nodes, short for "lymph nodes," are bean-shaped organs that are part of the body's lymphatic system. The lymphatic system makes and stores cells that fight infections. There are groups of nodes all over the body, including in the neck, armpits, and groin area.

Normally, nodes are small. You might not be able to feel or see them under your child's skin. But if your child's nodes get big and swollen, you might be able to. Big and swollen nodes are called "lymphadenopathy" or "lymphadenitis."

Nodes can get swollen over a few days. This is called "acute" lymphadenopathy or lymphadenitis. Nodes can also get swollen over weeks to months. This is called "chronic" lymphadenopathy or lymphadenitis.

This article discusses swollen nodes in the neck (figure 1). But children can get swollen nodes in other parts of the body, too.

What causes swollen neck nodes in children? — 

Different conditions can cause swollen neck nodes in children. The 2 main causes are:

●Infection – This is the most common cause. Different infections can cause swollen neck nodes. Some infections, such as the common cold, are caused by viruses. Others, such as some sore throats, are caused by bacteria.

●A condition that is not an infection – These can include diseases that affect certain tissues in the body (called "connective tissue diseases") or cancer.

What are the symptoms of swollen neck nodes? — 

Swollen neck nodes are large lumps you can see or feel on the front, sides, or back of your child's neck. They are sometimes painful, especially when touched. Also, the skin around swollen neck nodes is sometimes red or warm.

Children can have other symptoms, too, depending on what's causing the swollen neck nodes. For example, if the common cold is causing them, your child might have a runny nose, stuffy nose, or cough.

Should I call my child's doctor or nurse? — 

Yes. If you see or feel a swollen neck node on your child, tell their doctor or nurse.

Because different conditions can cause swollen neck nodes, the doctor or nurse will probably want to examine your child to find the cause.

Will my child need tests? — 

Maybe. The doctor or nurse will ask about your child's symptoms and do an exam. They might do tests to see what's causing the swollen neck nodes. The type of tests depends on how long the nodes have been swollen, if your child has swollen nodes in other parts of their body, and your child's other symptoms.

Tests might include:

●Blood tests

●Lab tests – For example, the doctor or nurse can use a cotton swab to get a sample from the back of your child's throat. Or if the node has pus in it, they can use a needle to get a sample of pus from the node. The samples are sent to a lab for tests.

●An imaging test, such as an ultrasound or CT scan – These create pictures of the inside of the body.

●Biopsy – The doctor removes the node or a small sample of tissue from the node. Then, another doctor looks at the sample under a microscope.

●A skin test for an infection called "tuberculosis" – This test involves getting a shot under the skin.

How are swollen neck nodes in children treated? — 

Treatment depends on what's causing the swollen neck nodes and your child's symptoms.

Most swollen neck nodes in children do not need treatment, because they are caused by the common cold. The nodes will get smaller when the cold gets better.

Swollen neck nodes caused by a bacterial infection usually need treatment with antibiotics. Most children can take these by mouth at home. But if your child has a severe infection, they might need treatment in the hospital. There, the doctor will give them antibiotics into a vein through a tube called an "IV."

If your child has a pus-filled neck node that doesn't get better with antibiotics, the doctor might need to drain the pus.
