Nasopharyngitis is inflammation of the throat, sinuses, and nasal passages. It describes a group of symptoms instead of a specific illness. Doctors may use "rhinitis" interchangeably with nasopharyngitis to refer to the common cold, which is caused by thousands of viruses. Bacterial infections in the sinus cavities, inner ear, and throat can also cause nasopharyngitis, as can fungal infections, though this is rare.
Most people are very familiar with the symptoms of nasopharyngitis: sneezing, coughing, sore throat, headache, and a runny or congested nose. Some people also experience post-nasal drip, watery or itchy eyes, a low-grade fever, tiredness, and muscle aches. These symptoms do not usually present a threat to long-term health but are irritating and can impact daily routine. Nasal secretions generally start as clear or white mucus and change to darker yellow or green discharge as symptoms progress. Symptoms generally fade after seven to 10 days.
