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 throat clearingmay indicate that you have allergies. If it happens only during a specific season, you are more likely to be a victim of seasonal allergies, which can be triggered by ragweed, pollen, mould, or other irritants that cause itchiness in the throat and inflammation in the nose. Constant tickling in your throat will make you want to clear your throat often.
