Heart Problem? Anxiety? Acid Reflux?

[kendraione]

I'm 30 year old female, always been in great health, but have a both sides of family history in depression and anxiety.   My symptoms are chest tightness or heaviness when I lay down on my back.  my heart feels like it's pounding hard.  sometimes shortness of breath, have gotten nausea from it a few times.  dizzy feeling. twinges of pain sometimes in left side of chest too.

And if, after a cardiac checkout, you are given a clean bill of health there, the next thing to do is get yourself under the care of a good psychiatrist for the familial anxiety.

In my considerable experience, that is the fastest way to *un-learn* being hyperaware of cardiac sensations.

Have you been evaluated by a cardiologist?  At your age, the changes of heart disease are lesser, but not impossible.
