These conditions occur together because of chronic inflammation in the nasal and sinus membranes.
If the symptoms have occurred for four weeks or less, it’s known as acute sinusitis.
When symptoms are present for four to 12 weeks, it’s known as subacute sinusitis.

However, when sinusitis persists at the 12-week mark and beyond, sinusitis is then called chronic rhinosinusitis.
ACT scanmay also be needed to diagnose chronic rhinosinusitis.
Usually a history of nasal congestion, chronic rhinosinusitis, and loss of smell may suggest nasal polyps.
Resting as much as possible will help your body fight the infection.
Also consider using saline nasal washes to clear stuffy nasal passages and warm facial compresses to soothe swollen sinuses.
And eating some hot chicken soup doesn’t hurt.
It affects 12% of the adult population worldwide.
Nearly 20% of people with chronic rhinosinusitis also have nasal polyps.
Nasal polyps are noncancerous (benign), soft sac-like tissue growths that occur inside the nasal passages.
They are usually teardrop-shaped growths, or they may appear together like a bunch of small grapes.
