Diagnosis

Your doctor will ask about your symptoms and medical history. He or she will do a physical exam.

Your doctor may want to do certain tests, such as:

  • Sinus x-rays—to identify abnormalities or a mass in the nasal region
  • Endoscopy—to examine nasal tissues
  • Blood tests—to check for anemia, low blood platelets, or clotting problems
