The lymphatic system is part of the body’s immune system that fights disease and infections. Lymph nodes are tiny, bean-shaped organs that help destroy infectious germs such as viruses and bacteria.
Swelling of the lymph nodes is a condition called lymphadenopathy. Swollen lymph nodes can be a normal occurrence and may not show an underlying disorder or condition or require treatment.
Lymphadenopathy occurs when lymph nodes in a specific area of the body (such as the head, neck, armpits, groin, abdomen or chest area) or throughout the whole body become enlarged. In children, swollen lymph nodes often appear as small, movable lumps under the skin. If a lymph node becomes very swollen, it may indicate an underlying illness.
Lymphadenopathy is a common response to illnesses such as an upper respiratory infection or strep throat.
Symptoms of lymphadenopathy may include:
- Swollen, enlarged lumps in the neck, back of the head, armpits, groin or chest area
- Fever
- A lymph node that is tender, feels hard or is draining pus
- Unexplained weight loss
- Recent illness
For a lymph node that is very painful or draining pus, see a doctor immediately.
Diagnosis of Lymphadenopathy
If your child has swollen lymph nodes, the doctor will do a physical examination and ask about:
- Symptoms and medical history
- Location of swollen nodes
- How long nodes have been swollen
- Pain
- Recent injuries or infections
Your child’s doctor determines if more tests, such as a lymph node biopsy, chest X-ray or blood tests, are needed.
Treatments
Treatments
There is no one treatment for lymphadenopathy. Treatment is based on the cause. Once your child's doctor has diagnosed the underlying condition that is causing the lymph nodes to swell, he or she will prescribe treatment based on the underlying condition.
