I'm a girl and I just turned fifteen this week. Since last year I have had a sudden heart pain that feels like an arrow has been shot at it and at the same time in had been punched. It lasts for a single heartbeat, then the pain gradually fades away. In the previous year it had been less frequent. Perhaps only once every month or so. It had lessened for a short while, but this year it had become more frequent, very, very painful, and it took longer to fade away. This month it had become a daily phenomenon sometimes more painful than others. I kept quiet because I now that my parents would thing that I'm faking it or exaggerating. I have noticed no pattern to it. And it comes suddenly and randomly. Please help. I'm sick of it!
