Hello and welcome, I understand your concern. If your are experiencing heavy breathing then it may be that the asthma is triggered. Colds are a common trigger factor for asthma. It can be easily controlled by using inhaled drugs like salmeterol and fluticasone. They can be obtained after prescription. So it is better to visit your physician and have the chest examined. A quick puff of these drugs will help control the symptoms. Hope this satisfies your query. Thanks for using HCM. Feel free to ask any more questions that you may have.
