Have you ever experienced a cold that just won’t quit?
Even after symptoms of throat and chest pain subside, it can take another few weeks for stuffiness and nasal discharge to clear up.
While this extra mucus and congestion can be normal in some cases, it can also be an indication of a sinus infection.
What Is Acute Sinusitis ?
Sinusitis is an inflammation, or swelling, of the tissue lining the sinuses. Normally, sinuses are filled with air, but when sinuses become blocked and filled with fluid, germs (bacteria, viruses, and fungi) can grow and cause an infection.
About 37 million Americans suffer from at least one episode of sinusitis each year (1).
The condition is typically caused by:
- Nasal mucous membrane swelling (caused by allergies or a cold)
- Blocked or narrow drainage ducts
- Nasal polyps
- Immune deficiencies, immunosupressant drugs or antibiotics
