woken up last night by sharp "tearing" chest pain, should I be really concerned? I am currently being evaluated for autonomic dysfunction.  My doctor got me in with a neurologist, but that's not till July.  Currently, my symptoms best fit with Postural Tachycardia Syndrome (also called Mitral Valve Prolapse Syndrome) and I also shown several signs of connective tissue disorder (possibly Ehlers-Danlos).  Anyways, I was a normal guy until my symptoms had sudden onset in January.  I've had chest pain before, but I've never been woken up by it.  It lasted for a couple minutes and then subsided, but comes back when I take a deep breath.  If it was a heart attack or aortic dissection/rupture then I'm pretty sure I would feel way worse than just chest pain.  It's on the left side, right over my heart and inward toward the edge of my sternum.  Any ideas?  Please no sarcastic answers, I'm already dealing with enough as it is.

Summarized question: What would cause the pain in the left side, right over my heart and inward toward the edge of my sternum?
