Some people are more likely than other to be diagnosed with asthma. Learn if you are at risk of asthma in this section on risk factors and causes of asthma....
I am having trouble when I take deep breaths or when I yawn. Whenever I try I end up coughing, I also have a tightness in my chest when I breathe. I am not a smoker or a drinker. I get out of breath going from one room in the house to another as well. What could be the cause?
I would go to a doctor about this, I think you have a chest infection, some anti-biotics should fix you up but if not you should discuss it with your doctor further. Wishing the best for you.
