Hi, I need some help. I'm a 25 year old female. 5ft 6, 105 lbs. Previously healthy, no family history of cardiac problems. For the past couple of years I have been suffering from severe left sided chest pain. It's sharp, sometimes radiates to my back and left arm. It occurs randomly. Always at rest. Lasts anywhere from a few seconds to a few minutes and will come and go throughout the day. Sometimes it even wakes me up in my sleep. I've had multiple normal EKGs, a stress test, echocardiograms, and worn a holter monitor. All came back normal but this won't go away. It causes extreme anxiety. Please help!
