If you have episodes of coughing, wheezing, shortness of breath, or chest tightness, have a complete checkup to find out what the problem is.
It could be asthma or another medical problem. Accurate diagnosis is important because asthma is treated differently from other diseases with similar symptoms.
Several tests may be needed to tell what is causing your symptoms. These tests include:
spirometry (to measure how open your airways are)
chest x-ray
electrocardiogram (to show whether you have heart disease)
blood test
