Hello. Some one please help. I have a sharp pain that comes and goes at rest. I've just had a stress test. Ultra sound of heart. Blood work. Ekg. Mammogram and chest exrays. All which I'm told is good. I do take medication for anxiety. And welchol for diaharea. And albutetol prn. When the sharp pain comes it only last for a few seconds. Could it be gerd. Acid reflux or what. Please help. As I'm not working and have no insurance. As I've lost my job. Thanks to all for any advice.
