I am suffering from a breathing difficulty from past 6 months.. i used to smoke during my college days not now. I am 28 year old now. My difficulty is observed as increasing after meals. My height is 175 and weight is 75. During the time of difficulty i cannot complete a long sentence without stress. Listeners also will feel suffocation by seing me. And one more thing , i am very well able to do excersises and i can run very long. But still i face this issue in an intervel periods.
