When to see a doctor for that cough

Coughs happen to everybody, all the time. With colds and viruses being passed around everyday, everywhere we go, how do you know when you might have something serious?

According to the American Academy of Family Physicians, there are several symptoms to watch for regarding a suspicious cough: it has lasted for more than three weeks, it includes green or yellow phlegm (or blood of course), or it comes with a fever or night sweats, wheezing when you breathe, or unexpected weight loss. Seek medical help as soon as possible if you're at all unsure -- most of us can tell if it's just a scratchy throat vs something more serious, but you should never take chances with your health.
