hi , thanks for your approach. I am sorry for your situation, I know it might be tough time for you to decide, you want to participate and you are feeling uncomfortable with physical functioning. the best result you can get is to check B.P and through ECG you will know the status of your physical health. As you said it might be for anxiety of match or any other previous reasons or experience. its better you visit both cardiologist and psychiatrist for better assessment and guidance. take care. wish you all the best for match. stay positive. one thing sometimes due to high gastric also there will be uneasy in chest.
