Symptoms can include a headache or pressure in the area of the sinuses, a stuffy nose, achy teeth, an odor coming from the nose, postnasal drip, cough, sore throat, laryngitis
, lightheadedness, constant low fever
, and thick, yellow to green nasal drainage.
The best way to identify a sinus infection is with a sinus CT scan, although sinus x-rays are a decent alternative. A sinus CT scan will also identify if any of the openings that drain your sinuses are blocked.
