Hi, I am a 29 year old male. 6 -180 lbs, excercise 3-4 days a week. I experienced mild chest pains about 4 years ago in my left chest area. No pain, just an uncomfortable feeling, but only when I was resting or not excercising. I had a stress test and echo and both came back negative. However I am experiencing the same feelings again. They come and go, but only when resting. The feelings Can last between 5-60 seconds. My fathers father has stable angina and is fine and my mothers father had a fatal heart attack at 38 years old. I have spoken to my doctor and he seems to think everything is fine. I have no radiating pain, headaches , or fatigue . The pain does not wake me up, but it s concerning giving my family history. Cholesterol and BP are normal. Any advice or suggestions would really be appreciated. Thanks for your help.
