1. How Severe Are Your Symptoms?
“Both the common cold and influenza can include upper respiratory symptoms such as sinus congestion, runny nose, sore throat and cough, as well as systemic symptoms including fever,” says Clifford Swap, MD, emergency medicine attending at Kaiser Permanente San Diego. However, flu symptoms tend to come on quickly and be more severe than in the common cold.
2. Are You Achy?
You may notice some mild aches and pains with a cold, but not to the degree you feel them if they’re flu symptoms. If you have the flu, your muscles and joints will hurt, often in your head, back, and legs. It could even be painful to move.
3. Are You Feverish?
While you may see the thermometer climb up to 99 or so, it is rare to have a high fever with a cold. Another sign of the flu is you usually—though not always—do see a fever, often in the 100 to 102 range (though that can be higher, especially in young children). Don’t be surprised if the fever lasts several days. Even though it feels awful, remember that fevers are your body’s way of fighting off the infection.
