I have been facing this problem of coughing after I run or jog or may be play badminton for sometime. I used to quiet active sometime back but now m not very active. So after playing badminton for 20 mins or running for 2 to 3 mins itself I start coughing. What could be this? Even when I used to be active I used to face this problem sometimes. But it used to solve itself after I used to regularly workout or do some kind of excercise. However, i feel it's quiet intense now. Please suggest as to what can be done in this regard or if I need to consult a doctor.
