Swollen Lymph Nodes in Children

Swollen lymph nodes are enlarged glands that can be felt under the skin, commonly in the neck, under the jaw, in the armpits or in the groin.

Viral and bacterial infections are common causes because lymph nodes enlarge as the immune system responds. Skin infections, dental problems, inflammation and less common medical conditions can also cause lymph nodes to swell.

When to see a doctor

Contact your pediatrician or another healthcare professional if:

  • A lymph node keeps growing or does not begin to shrink over time.
  • The lump feels hard, fixed or sits above the collarbone.
  • The skin becomes red, warm or painful.
  • Your child has prolonged fever, weight loss, night sweats or other unexplained symptoms.

Call 911 or get emergency care if:

  • Neck swelling affects your child’s breathing or swallowing.
  • Your child appears severely ill or has another life-threatening symptom.
