What is Sinusitis?
Inflammation of the tissue lining the sinuses is called sinusitis. Sinuses are normally filled with air, but when sinuses become blocked and filled with fluid, germs, bacteria and viruses can grow and cause an infection. The common cold, nasal polyps, allergic reactions or a deviated septum are all conditions that may cause sinus blockage.
Different types of sinusitis include:
- Acute sinusitis: A sudden onset of cold-like symptoms such as runny, stuffy nose and facial pain that does not go away after 10 to 14 days. Acute sinusitis typically lasts 4 weeks or less.
- Subacute sinusitis: An inflammation lasting 4 to 8 weeks.
- Chronic sinusitis: A condition characterized by sinus inflammation symptoms lasting 8 weeks or longer.
- Recurrent sinusitis: Several attacks within a year.
Some of the symptoms of acute sinusitis include:
- Facial pressure and pain
- Nasal discharge
- Loss of smell
- Bad breath
- Tooth pain
