I agree, it does kinda sound like heart palpitations. I had a pretty good case of them tonight, it was a sickening feeling of increased heart rate, a warm/burning feeling in my chest, mild pain, and indigestion (more than likely, heartburn and anxiety). It truly does feel far worse than what it actually is. Just another effect of anxiety, tension, and stress on the body.
But as always, with chest pain and anything heart related, it's best to get the opinion of a dr, which you did. Don't hesitate to see a different dr if it gets worse or increases in frequency.
