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.
I have had this a few times - twice I have been to ER ( A & E in England)thinking I was having a heart attack - in fact it was muscular and rib problems.
Since I have been on medication to ease the coughing this is no longer a problem
