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.
