This tutorial walks you through everything you need to know about sinusitis. We explain it in plain language, step by step, so whether you are a student, a patient, or simply curious, you will come away with a solid understanding.

We cover what it is, why it matters, how it is diagnosed, and what you can do about it. Key facts are called out along the way.

Sinusitis means your sinuses are inflamed. The cause can be an infection or another problem. Your sinuses are hollow air spaces within the bones surrounding the nose. They produce mucus, which drains into the nose. If your nose is swollen, this can block the sinuses and cause pain.

There are several types of sinusitis, including:

Acute, which lasts up to 4 weeks

Subacute, which lasts 4 to 12 weeks

Chronic, which lasts more than 12 weeks and can continue for months or even years

Recurrent, with several attacks within a year

Acute sinusitis often starts as a cold, which then turns into a bacterial infection. Allergies, nasal problems, and certain diseases can also cause acute and chronic sinusitis.

Symptoms of sinusitis can include fever, weakness, fatigue, cough, and congestion. There may also be mucus drainage in the back of the throat, called postnasal drip. Your health care professional diagnoses sinusitis based on your symptoms and an examination of your nose and face. You may also need imaging tests. Treatments include antibiotics, decongestants, and pain relievers. Using heat pads on the inflamed area, saline nasal sprays, and vaporizers can also help.
