Hello, I am male and age is 15 years. My height is 1.778 meters and my weight is 92 kgs. Today I was doing some exercise. First I did 200 skipping rope jumps and everything was normal. After that I was running on treadmill. My average pace was 10 km/hr. For the first two minutes everything was normal, but I was sweating a lot and I didn't catch my breath. I took some rest and after 2 min again I was on the treadmill. I was running for 1 min and at the last few seconds I got a pain near my heart and I had the sensation of vomiting. I think it is a pain of my artery and after 2 hours its still paining. But when I read it in the net they told me that something about coronary artery disease. I have short breath these days. Can you please help me.
