Asthma is a disease of the human respiratory system where the airways narrow, often in response to a "trigger" such as exposure to an allergen, cold air, exercise, or emotional stress. This airway narrowing causes symptoms such as wheezing, shortness of breath, chest tightness, and coughing, which respond to bronchodilators.
yes , coughing is a typical sign of asthma. So is wheezing.
your lungs and/or airways have been injured some and have inflamation by the irritants - colds, cigarettes, perfumes, etc. and will need time to heal.
you can google "asthma" on the internet for great reading materials.
