When should I see a doctor about a chest infection?

Chest infections – often called upper respiratory tract infections (URTIs) – often follow colds or flu. Most, like colds and flu, are due to viruses.

The main symptoms are:

  • A chesty cough – you may cough up green or yellow sputum
  • Wheezing and shortness of breath
  • Mild chest pain or discomfort
  • A temperature
  • A headache
  • Aching muscles
  • Tiredness.

These symptoms can be unpleasant, but they usually get better on their own in about 7 to 10 days. Most people do not need to see a doctor. Most people do not need antibiotics.

But You should see a doctor if you have a chest infection and:
  • You feel very unwell or your symptoms worsen
  • You have moderate/severe chest pain or short of breath or difficulty breathing
  • You cough up blood or have blood-stained sputum
  • You have a cough for more than three weeks
  • You have a very high fever – more than 39°C

  • You have a weakened immune system, such as from diabetes or chemotherapy
  • You have a long-term health condition, such as a heart, lung, or kidney condition (CKD)
