Questions about coughing after exercise, but good peak flows and spirometry
Hi. My son is 5 and was dx with asthma this past summer which was pretty surprising to me since he wasn't much of a cougher. However, this has changed dramatically. He has been coughing now for about the past 7 weeks. At night it was really bad, but the allergist put him on Flovent 2 puffs twice a day and then the Albuterol inhaler as needed. We also purchased a hepafilter for the bedroom. He has essentially stopped coughing at night, still coughing with a very loose cough in the morning, but nothing horrible. The really bad thing is that he can't run around for more than 5 minutes or so without getting horrible coughing spells that sometimes end up with him vomiting. Also, being out in the cold air is a problem too.
I am a little confused though. We were at the allergist last week and we had to wait a really long time so I took him out front (in the cold) as sitting in the waiting room was torture. When we came back in he had a coughing spell and the doctor did a breathing test and said his breathing was the best it has been (he had been on the Flovent about 2 weeks). So he said he was mucousy and prescribed a nasal inhaler. My son will not tolerate this so I called back today (after another episode of coughing after running around) and he prescribed Advair and told me to discontinue the Flovent.
My questions are:
1. If his asthma is under control with the FloVent as per what the allergist said this past Friday (when he had a breathing test after exercising in the cold, while having a coughing fit), should I be looking at other reasons for this coughing. Today after he had his coughing fit and vomited, I took his peak flow at home and it was 200, which was in a good range for him.
2. His cough after exercise sounds quite loose and not wheezy at all. Could he have mucous for another reason?
I am reluctant to up or change his asthma medications as he is essentially not coughing at any other time except when running around.
Also, he never complains of being short of breath.
