There are several factors that might contribute to throat congestion, including seasonal allergies, chronic bronchitis, and upper respiratory infections. Asthma, an illness known to constrict the upper airways, can also cause symptoms of congestion.
Infections â such as colds, influenza or sinusitis â allergies and various irritants, such as tobacco smoke, may all cause a runny nose. Some people have a chronically runny nose for no apparent reason â a condition called nonallergic rhinitis or vasomotor rhinitis (VMR). Less commonly, nasal congestion can be caused by polyps or a tumor. Other potential causes of nasal congestion include: 1  Acute sinusitis. 2  Bright lights. 3  Chronic sinusitis. 4  Churg-Strauss syndrome. 5  Cluster headache. 6  Cold temperature. 7  Common cold.
