Heather, if you were my daughter, I'd definitely suggest you go to a cardiologist to check out your situation. What you describe is not normal and if perhaps medication could fix the problem, then that would be your best route. My friend suffered from what you have described. She went through all the tests, and was given Cardizem and feels 100% better now on the pill. You are too young to have to go through this and worry. Rule out major problems - see a cardiologist and then you can have an answer to your problem and hopefully a reasonable solution. My best to you.
