I am 30 years old slim, do not smoke.  I have random chest pains on and off for around 6months.  I had ecgs, 2decho dopple, stress test and blood tests done.  The only issue was that my cholestrial level was a little high...I eat 2 many candys and drink 2 many soft drinks so wasnt that suprising.  I still get occassional chest pains, and after reading loads of info on the internet have become worried that waht if the tests missed soemthing.  I am now not sure what is wrong with me?
