Okay, so this thing with my heart has been happening for a while. I'm a 12 year old female, and I would like to know what this is and what the risks are. There is always times where I'm just enjoying a day, you know.. Normal activity's then I just basically stop, and my heart feels like there is someone squeezing and grabbing it, and it hurts to breath in really deep, It just recently happened around 5 minutes ago, and its still hurting. So this is very urgent if this is a worse thing than I thought. I don't think this is normal for a 12 year old to go through, and if it is something serious, tell me the risks and what I should do. Please, thank you.

What you should do is tell your mom about it, and ask her to make a doctor appointment.

We're out here in cyberspace, so we have no idea what is going on. It sounds like something that needs to be checked out.
