A sinus infection is an inflammation of the sinus cavities (spaces or air pockets) of the face. These sinus cavities are typically filled with air, but when inflamed can fill with mucus and produce facial pain and pressure.
The symptoms of a sinus infection can be similar to symptoms caused by allergies, including runny nose, nasal or eye discharge, and itchy eyes or nose. In general, a sinus infection can cause fever, whereas allergies would not.
Sinus infections are usually caused by a virus, bacteria, or fungus. Most sinus infections are caused by viruses and will get better with time, without the need for antibiotic treatment. Our medical team can help determine if your sinus infection might be caused by a bacteria and if you could benefit from treatment with an antibiotic. Bacterial infections, left untreated, can spread to other parts of the head. Rare complications of bacterial sinus infection can include infection to the eye or brain, causing blindness, meningitis, and rarely death.
