Swollen lymph nodes

, ,

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.

Description

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.

Self-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 seek immediate medical care

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.
