Does a runny nose mean your sick?

A runny or stuffy nose can be due to colds, allergies, sinus infections or the flu. When there is an excess of mucus secretions the nose is runny. The additional secretions drain from the front of the nose, or down the back (post-nasal drip).

Is a clear runny nose a cold?

A runny or stuffy nose with thin, clear fluid, accompanied by sneezing are common symptoms of a cold. A clear runny or stuffy nose and sneezing can also be seen in environmental allergies, which often also cause an itchy nose and itchy, watery, red or swollen eyes.

How long does a runny nose last?

After 2 or 3 days, mucus may change to a white, yellow, or green color. This is normal and does not mean you need an antibiotic. Some symptoms, especially runny or stuffy nose and cough, can last for up to 10 to 14 days. Those symptoms should improve over time.
