Me too. I used to get really bad chest pains as a kid and young adult. I don't get them any more, but I did not take notice as to when they stopped. I had my fillings replaced about 8 months ago and take magnesium now. The magnesium, aside from other things, has stopped my heart from racing which it used to do. I take CoQ10 which stops my heart from flip flopping which it used to do all the time. As to whether or not magnesuim and CoQ10 helped the pain, I don't know as the pain used to come and go.
