I think I have cough variant asthma. On cool mornings, I have a mild, productive cough that starts every morning after I get out of bed and lasts for about 15-20 minutes. I get the same type of cough after aerobic exercise. Usually, it lasts for about 15 minutes or until I take a warm shower, but after particularly intense exercise, it can last up to an hour and get quite irritating. During exercise, I do get a little short of breath, but no more (I think) than most people. I never actually have difficulty breathing. The coughing bothers my boyfriend more than it bothers me, so I mentioned it to my doctor last time I consulted her about something else. She suspected asthma and prescribed a ventolin puffer to test the theory. Taking a couple of puffs before I get out of bed and before exercise does seem to greatly reduce the coughing. But given that it wasn't really bothering me in the first place, am I better off ignoring it and avoiding unnecessary medication?
