I experience a typical probem - that of starting of abrupt coughing as and when I laugh heartily(deep breadth). Same thing happens if I exhert by running or any type of aerobic excercises. After exherting, I start coughing. I cough every time I inhale breadth. It settles down after some time. Another typical thing is that I cough immeditely after having a meal. Some cough also comes out at that time. In the past, during medical tests, my lung capacity has been detected as a bit less than normal. This test I must say was not reliable. But the docter had formed an opinion that I am a smoker, though I am a non-smoker, have no tobacco habits and am only an occasional drinker. I am generally a healthy person.
I am not getting a firm and convincing opinion on this condition, though I have no major problem due to this.
