Sinusitis is inflammation and swelling of the sinuses, the air-filled spaces around the nose, cheeks and forehead. It often follows a cold or flu and usually improves without antibiotics. Knowing what you can safely try at home—and when to seek help—can make recovery less stressful.
Common symptoms
Symptoms can include facial pressure or tenderness, a blocked or runny nose, reduced sense of smell, yellow or green nasal mucus, headache, toothache, cough and fever. Symptoms may affect one or both sides of the face. Coloured mucus alone does not prove that an infection is bacterial.
What causes sinusitis?
Most short-term cases occur after a viral respiratory infection. Swelling interferes with normal mucus drainage, creating pressure and congestion. Allergies can contribute, and some people experience repeated or persistent symptoms.
Self-care that may help
- Rest and drink enough fluids.
- Consider paracetamol or ibuprofen for pain or fever if these medicines are suitable for you; follow the label and ask a pharmacist if unsure.
- A saline nasal rinse may help some people. If preparing a rinse at home, use water that has been boiled and cooled, and make a fresh solution each time.
- Avoid smoking and known allergy triggers.
A pharmacist can advise whether a nasal spray or another treatment is suitable. Decongestant sprays should not be used for longer than the product instructions allow, as overuse can worsen congestion. Antibiotics are not routinely needed because many cases are viral.
When should you get medical advice?
Ask a pharmacist or GP for advice if symptoms are severe, keep returning, worsen, or fail to improve after the recommended period of self-care. Arrange medical advice if symptoms persist despite treatment. People with weakened immune systems should seek advice sooner.
Seek urgent medical assessment if you become very unwell, develop swelling or redness around an eye, changes in vision, a severe unusual headache, confusion or other signs that could suggest a complication.
How long does it last?
Acute sinusitis often clears within two to four weeks. If symptoms last for around three months or keep recurring, a clinician may investigate chronic sinusitis or other causes.
Key takeaways
Most sinusitis improves with time and symptom relief rather than antibiotics. A pharmacist can help you choose suitable treatments and recognise when further assessment is needed.
