Viral uri: A runny nose is most commonly caused by a viral upper respiratory infection. Other causes include allergies, excessive tearing (tears drain out the nose) and very rarely a leak of cerebrospinal fluid (usually only after trauma). Of these, only allergies are likely also to cause symptoms in your chest.
