How is acute sinusitis diagnosed?

Acute sinusitis is usually diagnosed by discussing all of your symptoms and medical history with your doctor. In a physical examine, your doctor will look at the ears, nose, and throat to check for any blockage, swelling, and drainage. If allergies are suspected, your doctor will have an allergy test performed to determine what allergens might be the cause of your sinusitis.
