Acute sinusitis (acute rhinosinusitis) causes the cavities around your nasal passages (sinuses) to become inflamed and swollen. This interferes with drainage and causes mucus to build up.

With acute sinusitis, it may be difficult to breathe through your nose. The area around your eyes and face may feel swollen, and you may have throbbing facial pain or a headache.

Acute sinusitis is most often caused by the common cold. Other triggers include bacteria, allergies and fungal infections. Treatment of acute sinusitis depends on the cause. In most cases, home remedies are all that's needed. However, persistent sinusitis can lead to serious infections and other complications. Sinusitis that lasts more than 12 weeks, or keeps coming back, is called chronic sinusitis.
