Sinusitis is an inflammation of the cavities called sinuses. Sinuses are air-filled spaces in the bones of the skull which open into the nose.
How do you get Sinusitis?
Acute sinusitis may follow an infection such as a cold or influenza, an allergy such as hayfever, an infection of the teeth, or changes in air pressure, for example when swimming underwater or travelling by air. Sinusitis can also result from a defect in the structure of the nose.
When the lining of the nostrils is swollen, the openings from the sinuses to the nose may be blocked, and the fluid in the sinuses cannot drain away, resulting in pressure, pain, headache and fever.
If the acute attack fails to clear up completely, then chronic sinusitis might develop.
How serious is Sinusitis?
Sinusitis is not serious but it can be very uncomfortable and painful while it lasts.
How long does Sinusitis last?
Sinusitis may last for several days during an episode when pain, headache and fever may be experienced. Afterwards, the nasal stuffiness and other symptoms may persist for one or two weeks.
How is Sinusitis treated?
Acute sinusitis will often get better on its own, but in severe cases may be treated with antibiotics to get rid of any infection, and with a nasal decongestant, which shrinks the swollen membrane lining the nose and makes it easier to breathe.
