I would be interested in anyone who has info on cough variant asthma. I have had asthma since 1997 and coughing is my only symptom. Prednisone is the only med that brings it under control. I have very severe dust mite, pollen, and dander allergies. Colds are the trigger to my most severe attacks. Laughing is also a trigger. Needless to say, this made for a lot of misdiagnoses from Dr's. I am interested in what anyone has to say SPECIFICALLY about cough-variant asthma, since everybody seems to associate asthma with symptoms like the ones on those Primatene commercials. Thanks.
