But a cold is generally mild, while the flu tends to be more severe.
Colds often starts with feeling tired, sneezing, coughing and a runny nose.
You may not have a fever or you may run a low fever-just a degree or two higher than usual. You may also have muscle aches, a scratchy or sore throat, watery eyes and a headache. As the cold worsens, your nasal mucus may turn from thin and watery to yellow and thick. Your symptoms may vary with each cold. A cold usually lasts three or four days but can last up to 10 days.
