Symptoms can include a headache or pressure in the area of the sinuses, a runny nose, 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.
