Sinusitis is swelling of the sinuses, the air spaces behind your cheeks, nose and forehead. It usually follows a cold and most cases clear up on their own within two to three weeks. Antibiotics only help a minority of people.

Imagine a cold that seemed to be ending, then a throbbing pressure behind your cheeks every time you bend down. That is classic sinusitis, and the right home care can make the next week far easier.

Symptoms

  • Pain, swelling or tenderness around the cheeks, eyes or forehead
  • A blocked nose and reduced sense of smell
  • Thick green or yellow mucus
  • Headache, toothache or bad breath
  • Sometimes a fever

What helps

  • Rest, fluids and paracetamol or ibuprofen
  • Saline nasal rinses or sprays to clear mucus
  • Decongestant sprays for short periods only (no more than about a week, or they can make congestion worse)
  • Warm compresses over the face

When antibiotics might help

Most sinusitis is viral. A doctor may consider antibiotics if symptoms last more than about 10 days without improving, are severe, or get better and then worse again. Many health services advise seeing a doctor if symptoms last more than three weeks, or keep coming back.

Get urgent help if you have

  • Swelling or redness around the eyes
  • Changes in your vision, such as double vision
  • A severe headache, stiff neck or confusion
  • A high temperature with feeling very unwell

But the mucus is green. Doesn’t that mean bacteria?

Not necessarily. Green or yellow mucus is common in viral infections too; the colour comes from your immune system at work. How long you have been ill and how severe it is matter more than colour.

Your next step: Try saline rinses and pain relief for the next few days. If you’re not improving after 10 days, are getting worse, or notice any eye swelling, see a doctor.
