Sinusitis

Sinusitis

0 medicines 11 symptoms

Sinusitis is when the sinuses become inflamed, meaning they turn red and swollen. The sinuses are small, air-filled spaces inside your cheekbones and forehead. When they are inflamed, they get blocked, so mucus cannot drain into your nose the way it normally does.

Sinusitis is usually caused by a viral infection. It is common, and it usually gets better on its own within 2 to 3 weeks.

Common Symptoms

Toothache bad breath (halitosis) blocked nose green or yellow discharge from your nose pain and tenderness around your cheeks, eyes or forehead high temperature (fever) of 38°c (100.4°f) or more reduced sense of smell be irritable breathe through their mouth have difficulty feeding sound nasal when they speak, as though they have a stuffy cold

When to See a Doctor

If your symptoms are mild and already getting better, you can usually manage sinusitis at home without seeing a doctor.

Do see a doctor if:

  • your symptoms are severe or getting worse
  • your symptoms have not started to improve after around 7 to 10 days
  • you keep getting sinusitis again and again

Causes

What causes sinusitis?

Sinusitis is usually caused by a cold or flu virus spreading to the sinuses from the upper airways. Only a few cases are caused by bacteria infecting the sinuses.

An infected tooth or fungal infection can also occasionally cause the sinuses to become inflamed.

Chronic sinusitis

It’s not clear exactly what causes sinusitis to become chronic (long-lasting), but it may be related to:

  • allergies and related conditions, including allergic rhinitis, asthma and hay fever
  • nasal polyps (benign growths inside the nose)
  • smoking
  • a weakened immune system

Controlling underlying conditions like allergies may improve the symptoms of chronic sinusitis.

Don’t include personal information e.g. name, location or any personal health conditions.

Diagnosis

Diagnosing sinusitis

Your GP will usually be able to diagnose sinusitis from your symptoms and by examining the inside of your nose.

If you keep getting sinusitis, or its severe, they may refer you to an ear, nose and throat (ENT) specialist.

Treatment

Sinusitis usually clears up on its own within 2 or 3 weeks.

Treatments from your doctor

If your symptoms are not improving, or are getting worse, your doctor may prescribe antibiotic tablets or a corticosteroid spray or drops.

If your symptoms still do not get better, you may be referred to an ENT specialist for surgery to improve the drainage of your sinuses.
