I m a 15 year old girl. About two/three weeks ago, I got an extremely bad pain in my heart , and I could barely move or breathe. My parents said it was heart burn, but I ve had heart burn and this felt a lot worse. Then just two days ago, I was sitting outside with a friend and all of a sudden my heart starting hurting like it did a few weeks ago. I nearly stopped breathing, and I kept putting my head down and it felt like I was semi-passing out. My friend started blowing on me and forcing me to breathe, eventually I did, but it was so difficult. My feet started hurting really bad, I don t know if that has anything to do with it or not though. Ever since those two days ago, it s been slightly harder to breathe than usual. Help?
