I looked this up on the link provided and this sounds exactly like what my 6/7 year old has been suffering from for the last 4 years and no one would diagnose him with asthma. They kept telling me to give him cough meds and cold meds and they never worked and being an asthmatic myself I knew better. He would reach a point where he would cough like 10 -15 times a minute and I would wind up taking him to ER clinic and they would give him a treatment and off we would go. They said there was no wheezing or major shortness of breath but the coughing would get so bad he would vomit and couldn't catch his breath. Finally Easter before last a new doctor at the ER clinic asked "why hasn't this child been diagnosed with asthma" she wrote me a scrip for a nebulizer and some prednisone and we have been treating him ever since. I got rid of his original pediatrician. I never knew there was such a thing as cough-variant asthma. geez thanks you guys.
