It isn't common for young fellows your age to have heart attacks. But, it does occur. Why take the risk?
Go to your doctor or to the er let them give you an ekg. They can see if there are any abnormalities in your heart or if your heart is receiving insufficient blood flow.
If they conclude that it isn't the heart. Then it may just be anxiety and stress. If that is the case, you must teach yourself techniques to relax and enjoy. Stress and anxiety do lead to heart attacks. If not now, then in twenty years from now. You might as well learn how to relax, before the heart strikes.
I am responding to you as a heart attack survivor. And I had my first heart attack when I was 37 years old. Learn from the experienced.
