[|AI|]  Hello Thanks for posting at Chat Doctor. In view of your young age and symptoms of chest tightness and breathlessness, the suspicion points more towards asthma than a cardiac cause. Please do a pulmonary function test which requires you to blow into a machine and your lung capacities are recorded. Next thing recommended is a chest x-ray. PFT will show functional capacity of the lungs and x-ray will show if there are any associated lung issues. I do not suspect ant cardiac issues here but if you are very concerned you can do an ECG. Please do the above tests and revert with the results. Wishing you good healthRegards
