Runny Nose and Nasal Congestion
Though a runny and stuffy nose is a common indicator of the common cold, flu also causes these symptoms. However, flu symptoms tend to be more severe compared to a common cold and include high temperatures (above 102 F), cough without phlegm, chills, body aches, and lack of appetite. Unlike other flu symptoms, nasal congestion does not start abruptly but typically appear over 1 to 2 days.
