About a year ago I started having discomfort in my chest. I was 32 years old and very alarmed. After two visits to the ER (Once kept over night for observation), I also had several EKG's, a stress test, an echocardiogram, full blood work, an ultrasound of my abdominal area and a CT Angiogram all of which came back "normal". My Family Doctor and Cardiologist have said it is not a heart issue but did put me on 75 mg of Metoprolol (50 in the morning and 25 at night) for elevated blood pressure and heart rate. Both are in the normal range now, but I still have fairly regular chest discomfort and lightheadedness, some days are better than others. Any advice on what I should do? Thanks for your time.
