Sinus infection and its symptoms

Sinusitis refers to inflammation of the sinuses and can lead to a variety of unpleasant symptoms, such as headaches or blocked noses.

In our skull are a number of cavities lined with mucosa. They serve a variety of functions which include warming and humidifying the air that we breathe through our nose. Mucus, dust and bacteria are also trapped in nasal secretions and swept away by the cilia.

When we experience nasal congestion, the mucous membranes in the nasal cavities swell and the connection between the paranasal sinus' and the nasal cavity can become obstructed. The bacteria, find themselves trapped in warm, dark and humid areas. These become the perfect breeding ground where they can then freely multiply, which is why a sinus infection may develop quicker than you notice the accompanying symptoms.
