What is sinusitis?
Sinusitis is an inflammation of the sinuses, the bones that communicate with the nasal cavity. When the sinuses close, mucus builds up and causes inflammation. Causes of sinusitis include a bacterial, fungal or viral attack or swollen turbinates, which in turn causes obstruction of the sinuses.
This swelling is often due to contact with irritants such as smoke, chlorine or dust. Allergies can also be a cause of sinusitis, as inflammation causes mucus to build up.
What are the symptoms of sinusitis?
Sinusitis can manifest in many ways, the most common are:
- Headache
- Pain in the face and around the eyes
- Tearing
- Nighttime cough
- Fever
- Nasal congestion
Frequently, a general discomfort is experienced. Hearing may also be affected by the infection. In fact, nasal obstruction prevents air from properly passing through the the eustachian tube, the canal that connects the ear to the nasopharynx, thus prompting an ear congestion. Tinnitus can be another symptom of sinusitis.
