Flu vs. Cold
Differentiating a cold from the flu by symptoms alone can sometimes be difficult or impossible, but in general, people with the flu get sick more suddenly, look much sicker, and feel much weaker than if the ailment were a common cold. Higher fever, body aches, extreme tiredness, and dry cough are more often symptoms of the flu, whereas runny or stuffy nose are more often associated with common colds.
