Sinuses are a series of connected hollow cavities in the skull. A sinus infection or sinusitis typically occurs after a common cold, allergic rhinitis, nasal polyps or a deviated septum.
This creates an environment where the sinuses become blocked and fill with fluid, bacteria, viruses or fungi that grow and cause an infection.
Sinus infections can affect all age groups. Symptoms include facial pain or pressure, nasal stuffiness, nasal discharge, loss of smell, foul smell, cough, congestion, fever, bad breath, fatigue and dental pain.
Types of Sinus Infections
There are two types of sinus infections.
- Acute sinus infection symptoms last up to four weeks and are usually caused by a virus or bacteria.
- Chronic sinus infection symptoms last 12 weeks or longer and are usually caused by prolonged inflammation.
An untreated sinus infection typically leads to unnecessary pain and discomfort. In rare cases, an untreated sinus infection can lead to meningitis or brain abscess and bone infection.
