Sinusitis
The swelling or inflammation of the tissue lining the sinuses is known as sinusitis. Mucus produced by the sinuses keeps the inside of your nose moist. Consequently, that aids in defense against pollutants, dust, and allergies.
Air is present in healthy sinuses. However, bacteria can proliferate and create an infection when they become clogged and filled with fluid.
Sinus obstruction can result from the following conditions:
- The common cold
- Allergic rhinitis, which is swelling of the lining of the nose caused by allergens
- Small growths in the lining of the nose called nasal polyps
- A deviated septum, which is when the nasal cavity is crooked
