A sinus infection occurs when the fluid becomes trapped in the sinus cavity causing increased pressure or pain. A majority of the time (90%) a sinus infection is caused a virus, and therefore an antibiotic is not needed for treatment.
Risk Factors. A previous respiratory tract infection, a weakened immune system, and a history of allergies or nasal polyps may all increase your risk of getting a sinus infection.
Symptoms. The most common symptoms of a sinus infection are headache, stuffy or runny nose, loss of the ability to smell, facial pain or pressure, postnasal drip, sore throat, fever, cough, and fatigue.
When to Seek Medical Care. Be sure to visit your doctor or local urgent care clinic if you experience a temperature >100 degrees; symptoms that have not improved within 10 days; or multiple sinus infections within the past year.
Treatment. In the rare occasion that your sinus infection is caused by a bacteria, antibiotics may be prescribed. Otherwise, rest, OTC medications, and self-care should help provide symptom relief while the virus runs its course. Warm compresses to the nose or forehead, or breathing in steam from a bowl of hot water or shower should help to relieve sinus pressure. Decongestants and nasal sprays may also help with nasal congestion if needed.
