I have gas problems along with it when I go through stairs or doing excercise my heart rate gets fast and I aware of it and due to it I feel panic also my mind full focus on it also from it I feel some breathing issue. But my main problem is I don't excercise like before like everyone does I got worried to do excercise or hard work as my heart rate gets fast and I panicked with it. What should I do how to cure it. Also I did medical tests and found all my tests are okay including ECG. Also I feel gas problems from which my heart rate get fast in sometimes while rest or other works.
