Question: is a dry tickly cough a sign of asthma?
Answer: Cough-variant asthma is a type of asthma in which the main symptom is a dry, non-productive cough. (A non-productive cough does not expel any mucus from the respiratory tract.) People with cough-variant asthma often have no other "classic" asthma symptoms, such as wheezing or shortness of breath.
