If you suspect you (or someone in your care) has asthma, you should visit a nearest primary care physician to get an accurate diagnosis. The clinician will do a number of tests to determine if you have asthma and to also make sure you are not mistaking asthma for something else.
You may be diagnosed with asthma if:
You have frequent periods of coughing, wheezing or shortness of breath
You get "chest colds" that take 10 or more days to recover
You have a family history of asthma or allergies
