Swollen glands

Swollen glands are a sign your body is fighting an infection. They usually get better by themselves within 2 weeks.

Symptoms of swollen glands

Swollen glands feel like tender, painful lumps:

Sometimes viral infections can cause swollen glands, such as glandular fever.

Treating swollen glands

Swollen glands should go down within 2 weeks.

You can help to ease the symptoms by:

  • resting
  • drinking plenty of fluids (to avoid dehydration)
  • taking painkillers like paracetamol or ibuprofen


Do not give aspirin to children under 16

Do not self-diagnose, contact your GP if you're worried.

When to contact your GP

Non-urgent advice: Talk to your GP if:

  • you have swollen glands and you find it very difficult to swallow
  • your swollen glands are getting bigger or they have not gone down within 2 weeks
  • your glands feel hard or do not move when you press them
  • you're having night sweats or have a very high temperature of 38 degrees Celsius or above for more than 3 or 4 days
  • you have swollen glands and no other signs of illness or infection
  • you have swollen lymph glands just above or below your collar bone (the bone that runs from your breastbone to each of your shoulders)

Your GP will recommend treatment depending on the cause of your swollen glands. This may include antibiotics.

Antibiotics do not work if the cause of your swollen glands is a viral infection.
