What Is Sinusitis?

Sinusitis is an inflammation or swelling of the tissue lining the sinuses. Healthy sinuses are filled with air. But when they become blocked and filled with fluid, germs can grow and cause an infection.

Conditions that can cause sinus blockage include:

Types

You may hear your doctor use these terms:

  • Acute sinusitis usually starts with coldlike symptoms such as a runny, stuffy nose and facial pain. It may start suddenly and last 2-4 weeks.
  • Subacute sinus inflammation usually lasts 4 to 12 weeks.
  • Chronic inflammation symptoms last 12 weeks or longer.
  • Recurrent sinusitis happens several times a year.

Who Gets It?

Lots of people. About 35 million Americans have sinusitis at least once each year. It’s more likely if you have:

  • Swelling inside the nose like from a common cold
  • Blocked drainage ducts
  • Structural differences that narrow those ducts
  • Nasal polyps
  • Immune system deficiencies or medications that suppress the immune system

For children, things that can cause sinusitis include:

  • Allergies
  • Illnesses from other kids at day care or school
  • Pacifiers
  • Bottle drinking while lying on the back
  • Smoke in the environment

The main things that make sinusitis more likely for adults are infections and smoking.

Acute Sinusitis Symptoms

The main signs include:

  • Facial pain or pressure
  • "Stuffed-up" nose
  • Runny nose
  • Loss of smell
  • Cough or congestion

It may be acute sinusitis if you have two or more symptoms, or thick, green, or yellow nasal discharge.

  • A feeling of congestion or fullness in your face
  • A nasal obstruction or nasal blockage
  • Pus in the nasal cavity
  • Fever
  • Runny nose or discolored postnasal drainage

You may also have headaches, bad breath, and tooth pain. You may feel tired a lot.

Lots of things can cause symptoms like these. You'll need to see your doctor to find out if you have sinusitis.

Treatment

If you have a simple sinus infection, your doctor may recommend you use a decongestant and saline nasal washes. You shouldn’t use an over-the-counter decongestant more than 3 days, though, because it can make you more congested.

If your doctor gives you antibiotics, you’ll probably take them for 10 to 14 days. The symptoms usually disappear with treatment.

Warm, moist air may help if you have chronic sinusitis. You can use a vaporizer, or you can inhale steam from a pan of warm water. Make sure the water isn't too hot.

There are some other things you can do yourself to help with chronic sinusitis:

  • Warm compresses can ease pain in the nose and sinuses.
  • Saline nose drops are safe to use at home.
  • Over-the-counter decongestant drops or sprays can help. Don’t take them longer than recommended.

In some cases, your doctor may prescribe steroids along with antibiotics.

Other Options

You also need to avoid any triggers linked to your sinusitis. 

If you have allergies,your doctor may recommend an antihistamine.

If a fungus is to blame, you’ll get a prescription for an antifungal medicine.

If you have certain immune deficiencies, your doctor may give you immunoglobulin, which helps fight the things your body reacts to.

Can I Prevent Sinusitis?

There is no sure-fire way to prevent sinusitis. But there are some things that might help.

  • Don’t smoke, and avoid other people's smoke. 
  • Wash your hands often, especially during cold and flu season, and try not to touch your face.
  • Stay away from things you know you’re allergic to.

What Happens if Sinusitis Isn’t Treated?

You’ll have pain and discomfort until it starts to clear up. In rare cases, untreated sinusitis can lead to meningitis, a brain abscess, or an infection of the bone. Talk to your doctor about your concerns.
