Sinus Infections

Chronic Sinusitis

Diagnosis of sinus infections (called sinusitis) is made based on the symptoms and the physical examination. Symptoms of a sinus infection include pain and pressure in the facial region or behind the eyes, fever, purulent nasal discharge with increased post-nasal drainage and nasal congestion. If the infection is quite severe it can lead to redness and swelling of the skin near the eyes. Headaches can of course be caused by many conditions other than sinusitis, so it is important to try to confirm the diagnosis of a sinus infection.

Physical examination is useful, but it is difficult to actually see into the sinuses in someone who has not had previous sinus surgery. In some cases one can actually see pus coming out of the sinuses, which confirms the diagnosis.
