Dear Sir, I am of 28 years old. I have a problem of brathing while inhaling at some times, not continuosly specially when to have a continous discussion & communication with frends and othe people and feel suffocation . Even when to going upstairs of 4th floor apartment. it roots from back 5 years, started, when during teaching, (when i was a teacher), my throat was struk up, so after continous teaching & speaking with students, at the end of night, while going to sleep , feeling to tired off, or feeling imbalecment during breathing , but not much problem. Now i am doing a job in a private industry. i quit teahing since back three years. but have a problem of breathing while, walking, upstainring and to talks and chats with my friends, not continuous but at some times. while talking with my friends, i stop and take long & suffocated breath.
