About Rhinosinusitis
Rhinosinusitis is a swelling of the nose and sinus passageways that typically lasts weeks to months. This condition causes a stuffed or blocked nose that creates breathing difficulties, thick yellow or green mucus in the nose or throat, pain, aching, or swelling in the face, eyes, or forehead, a weakened sense of smell, and trouble sleeping. (1) Many factors can trigger or cause rhinosinusitis, including an overactive immune reaction, type 2 inflammation, nasal polyps, allergies, asthma, exposure to smoke or pollution, or a crooked septum.
Types of Rhinosinusitis
There are two main types of rhinosinusitis: acute and chronic.
Acute rhinosinusitis lasts less than four weeks, and you may experience a stuffy nose, facial pressure, yellow or green mucus, and loss of smell. Most of the time, it will improve in about a week or ten days with simple care.
Chronic rhinosinusitis typically lasts 12 weeks or more and is caused by allergies, swollen nasal tissue, or lasting infections. You may experience ongoing stuffiness, thick mucus, a lingering cough, or dull facial aching.
