A Wheezing sound is a kind of a whistle sound coming from chest; it may be in form of Cough. If this sounds familiar, you could have asthma. Allergens inflame the airway, squeezing the muscles around it and leaving you short of breath. If you experience coughing and wheezing only at the gym, you may have exercise-induced asthma. See a doctor whenever you experience coughing and wheezing together, or if you have a cough that lasts for more than four weeks or wakes you up at night. These could be other silent signs of acid reflux you're ignoring.
