Sinusitis

Sinusitis is caused when the sinuses become inflamed which can cause pain, a headache and a runny nose. Sinuses are spaces in the skull, behind the cheeks, nasal bones and forehead, that are normally filled with air and lined with mucous membranes.

When your sinuses are healthy, they contain no bacteria. Mucus is able to drain out and air is able to circulate. However, if they become blocked through inflammation they can become infected.

Types of sinusitis include:

• Acute sinusitis
  Symptoms are similar to a cold and can include a runny nose, headache and facial pain. Usually this last no more than a week and it is often caused by a virus. Sometimes there is a secondary bacterial infection, which can lead to acute bacterial sinusitis

If you have frequent sinusitis or your infection lasts for more than 12 weeks it could be chronic sinusitis.

• Chronic sinusitis
  Symptoms of chronic sinusitis can be caused by bacteria or a fungus and are the same as for acute sinusitis but are usually milder.

If it is untreated, chronic sinusitis can damage the sinuses and cheekbones and may sometimes need surgery.
