How is sinusitis diagnosed?
Your healthcare provider will ask you a lot of questions in order to develop a detailed medical history and find out about your symptoms. They will also do a physical examination. During the exam, your care provider will check your ears, nose and throat for any swelling, draining or blockage. An endoscope (a small lighted/optical instrument) may be used to look inside the nose. In some cases, you might be referred to an ear, nose and throat (ENT) specialist. If you needed an imaging exam, your provider would order a computed tomography (CT) scan.
