What is sinusitis?

Sinusitis is often the consequence of a cold and can be accompanied by fever. The inflammation often begins in the nose. Since the nose is connected with the sinuses through narrow passages, the infection spreads easily to the adjacent cavities.

The nasal cavities are air-filled gaps in the skull bone. Like the nose, they are lined with a mucous membrane. We speak about sinusitis when the mucous membrane is inflamed.

A typical symptom of sinusitis is a headache, especially around the forehead and below the eyes. This often leads to a marked feeling of pressure that increases when bending down. The nose feels clogged and the sense of smell is impaired.
