I've been having frequent chest pains since last month specially at night time. I've done many ECGs and 2d Echo test done but it's WNL. Doctors say it could be due to acicidity or muscular pain. I think they are also not sure and keep telling me there is nothing wrong with with your heart you are most probably thinking too much about the problem. Is it due to stress or other psychological problem because I live separately from my wife and I am in sort of mental stress please diagnose my proble
