A viral infection (the common cold) is the most common cause of a stuffy and/or runny nose, but allergies, influenza, and sinus infections also may cause these symptoms. Less commonly, anatomical obstructions (e.g. a deviated nasal septum, foreign bodies) may lead to nasal congestion.
Constant swallowing is among the primary post-nasal drip symptoms. Swallowing occurs so often with a post-nasal drip because the back of your nose and throat will need lubrication. The excess mucus in the nasal drip can dry out the throat. This also tends to cause a feeling of fullness in the stomach and bad breath. Rhinorrhea is very common for people who have a nasal drip.
