Swollen lymph nodes
Updated: 2023-08-18
Description
Lymph nodes are immune system glands that usually swell in response to a bacterial or viral infection. Rarely, swollen lymph nodes are caused by cancer.
Self-care
Rest, and apply a warm, moist compress to the swollen area. Pain relievers available without a prescription also may provide relief, but don't give aspirin to children.
When to seek immediate medical care
Seek medical care immediately if swollen lymph nodes are accompanied by:
- Sore throat or difficulty swallowing.
- Trouble breathing.
- Redness or pain in the area of the lymph nodes.
When to make a doctor's appointment
Make an appointment to see a health care professional if swollen lymph nodes:
- Have no obvious cause.
- Grow and are painful.
- Last for 2 to 4 weeks.
- Feel hard or rubbery or seem fixed to the skin.
- Are accompanied by persistent fever, night sweats or unexplained weight loss.
