Chronic sinusitis is a common condition in which the cavities around nasal passages become inflamed and swollen despite treatment attempts.

Your sinuses are hollow air spaces within the bones surrounding the nose. They produce mucus, which drains into the nose. If your nose is swollen, this can block the sinuses and cause pain.



There are several types of sinusitis, including

Acute, which lasts up to 4 weeks
Subacute, which lasts 4 to 12 weeks
Chronic, which lasts more than 12 weeks and can continue for months or even years
Recurrent, with several attacks within a year

Acute sinusitis often starts as a cold, which then turns into a bacterial infection. Allergies, nasal problems, and certain diseases can also cause acute and chronic sinusitis.
