Acute sinusitis is a short–term inflammation of the sinuses, often accompanied by an infection. The sinuses are cavities or spaces in the head, linked by tiny channels that produce thin mucus to clean the nose. When the sinuses become inflamed, they can enlarge and fill up with fluid, causing mucus to accumulate and drainage to be obstructed. This can make it difficult to breathe through the nose and cause facial swelling, pain, and headaches. Sinusitis is also known as rhinosinusitis because nasal tissue is often affected along with sinus tissue.
Acute sinusitis is usually caused by the common cold and usually clears up within a week to 10 days, unless it develops into a bacterial infection. Home remedies can often treat acute sinusitis effectively. If sinusitis lasts for more than 12 weeks despite medical treatment, it is classified as chronic sinusitis.
