To diagnose sinusitis, your doctor will review your symptoms and give you a physical examination.
The exam may include the doctor feeling and pressing your sinuses for tenderness. He or she may also tap your teeth to see if you have an inflamed paranasal sinus.
Other diagnostic tests may include a study of the mucus culture, nasal endoscopy (see below), X-rays, allergy testing, CT scan of the sinuses, or blood work.
