A few years ago when I was in my middle teens, I was diagnosed with Mitral Valve Prolapse. I never went on medicine for it, and would just take asprin if I ever had discomfort. Over the past 3 weeks, I've been having sharp chest pains nearly everyday. Over the past 6 months, the pain has gone down into my left arm, I got so used to this, that I didn't think anything of it. Now, that the pain comes everyday and sometimes is leading into my left arm, I'm getting worried.
