Can you please tell me about the actual symptoms of the flu and how do they differ from those of a common cold?

Sicker with flu: With true influenza, in addition to the runny/stuffy nose and congestion, you also get a much worse cough, chest tightness, fever is much higher and much more of headaches and body aches with influenza. While a cold is irritating and you feel under the weather, influenza makes you feel like you have been hit by a truck and run over again!
