What is Sinusitis?

A sinus infection, or sinusitis, is inflammation of the tissue lining the four paired sinus cavities: ethmoid, frontal, maxillary, and sphenoidal. The lining of the sinus cavity usually produces a thin mucous that helps keep the cavities free of foreign material including viruses and bacteria. Acute bacterial sinusitis often occurs after a typical upper respiratory infection or a cold. The symptoms that precede sinusitis can include a runny nose, sore throat, fever, chills and fatigue and usually last for 10 days or greater. Chronic sinusitis are the same symptoms as acute but last for more than 12 weeks.

Those with a history of nasal polyps, allergies, asthma, or abnormal nasal anatomy may be a higher risk for this infection than others. It can be difficult tell the difference between a cold and sinus infection but the presence of fever, green nasal discharge and facial or tooth pain tend to favor sinusitis over a simple cold. Sinusitis can be caused by bacteria, viruses, or fungi. Your urgent care provider will help determine the cause and direct you towards the proper treatment.

How is a sinus infection treated?

The treatment will depend on the cause, but most are bacterial in nature and will require an antibiotic. Decongestants, improving hydration, nasal saline and steroids also play a role in the treatment of sinus infections. If the treatment doesn’t help resolve the issue, a CAT Scan can be ordered to evaluate the anatomy and extent of the infection.
