Aside from a stuffy nose and some general muscle aches, a cold or the flu shouldn't make you short of breath or cause pain in your chest. These could be signs of a more serious problem such as heart disease, asthma, or pneumonia. Call your doctor or go to the emergency room.
Flying to great-aunt Erma's house for Thanksgiving? Or taking a leisurely wintertime cruise along the shores of the Mexican Riviera? Boost your chances of healthy travel by taking a few preventive steps. That way, you'll cut your risk of catching cold and flu from other plane passengers. And you won't be confined to your cabin on the cruise ship, battling a nasty case of gastroenteritis while other passengers are off enjoying the sights.
A cough that won't go away is likely postnasal drip that can be treated with antihistamines. But it could also be related to asthma or GERD (gastroesophageal reflux disease). Your doctor can tell you about treatments that can help.
A lasting, severe cough is also the main symptom of whooping cough, which has become more common in many parts of the U.S. So, if you have an unexplained cough for more than 2-3 weeks, your doctor may test you for this type of infection.
