General Information on Sinus Infections (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 the challenge is to determine it they are due to some problem with the sinuses.

If you experience a smell or taste problem, it is important to remember that you are not alone. More than 200,000 people visit a doctor each year for a smell or taste problem. Many more smell and taste disturbances go unreported.
