- Sinusitis is inflammation of the sinuses, air-filled cavities within the face and skull bones.
- Sinusitis can present with headache, tooth pain, facial pressure, thick drainage and reduced sense of smell. It often coincides with nasal symptoms as the two spaces are connected.
- Sinusitis may be caused by allergies, infections, air pollution or structural problems in the nose. Rarely, recurrent sinus infections can indicate an immune deficiency.
- Most infections are caused by viruses and do not require antibiotics. Symptoms lasting more than 10 days, high fever, or disease that improves and then gets worse may be signs of a bacterial infection.
- Allergic sinus disease can often be treated similarly to allergic rhinitis. This may include allergen avoidance, medications or shots.
