Sinusitis, or a sinus infection, affects over 30 million people in the U.S. every year. It causes pressure behind the eyes, eyebrows, and cheekbones when the tissue lining the skull's cavities becomes inflamed. While it can often be remedied with over-the-counter medications, understanding this condition can help determine when to see a doctor. Here's what to know about it.

A Guide to Sinus Infections 

What causes a sinus infection?

When a person is healthy, mucus circulates throughout the empty spaces behind the cheekbones and forehead. In these areas, cells called cilia sweep irritants like dust, microbes, and allergens down the throat to the stomach. 

If bacteria, viruses, or fungal infections get inhaled, germs can start to grow. These irritants can cause the mucosal lining to become inflamed, preventing cilia from eliminating them from the sinuses. Common conditions that make you more prone to blockage and infections are colds, allergic rhinitis, nasal polyps, or deviated septums.

What are the signs of sinusitis?

Many people with sinus infections experience facial pressure and a headache. Other common indicators of the condition include a stuffy nose, post-nasal drip, sore throat, loss of smell, fatigue, cough, ear pressure, and yellow or green mucus. Less commonly known afflictions are fever, bad breath, and dental pain.

For acute sinusitis, these symptoms last no more than four weeks. In contrast, they can continue for at least 12 weeks if you have a chronic condition.

Is a sinus infection contagious?

Whether or not sinusitis is contagious will depend on the type of infection. If bacteria, such as Streptococcus pneumonia, cause the condition, it will not spread to others. On the other hand, a viral sinus infection, which often results from the common cold or flu, is contagious. 

To prevent infecting others, wash your hands frequently, wipe down shared surfaces with disinfectant, and cover your nose and mouth when coughing or sneezing.

How can I treat it?

Many cases of sinusitis can be treated without antibiotics. Using an over-the-counter decongestant and a saline nasal wash will help flush out the cavities. Home remedies to soothe discomfort include utilizing a vaporizer or inhaling steam from a bowl of hot water to open nasal passages. A warm compress around the nose can alleviate pressure, while drinking plenty of water keeps the mucus thin. For chronic sinusitis or sinus problems that persist, see an ENT specialist for further treatment.
