Diagnosing Asthma: How to know if Your Cough is Asthma

More than 20 million people in the United States suffer from asthma. If you are one of those who have asthma, the first symptom that you might experience is a persistent nighttime cough that you cannot seem to quiet. Of course, that cough could very well be a sign of another respiratory disorder as well. So how do you tell the difference? The answer will probably require a trip to your doctor for a further evaluation to determine whether your cough is indeed caused by asthma.
