J01.8: Other acute sinusitis
The sinuses are cavities in the skull that are filled with air. They make the head lighter and influence the sound of the voice. Air is moistened and warmed up in the sinuses. The sinuses have an inner lining of a moist and smooth membrane. This inner membrane is also called the mucous membrane. The mucous membrane produces fluid. The sinuses are connected to the nose via an opening. As a result, fluid can run out of the sinuses into the nose.
You have an inflammation in several of your sinuses.
When there is an inflammation, the mucous membrane swells up. The swelling can block the connection to the nose. As a result, fluid accumulates in the sinuses. This can cause headaches, fever and abnormal fatigue.
