question: what heart problems could i possibly have if i feel; chest pains like someone is hugging me too tightly or like my chest is collapsing. i also get dizzy/light headed sometimes. my chest pains make me feel like i cant breathe the way im supposed to. also, with my chest pains when i inhale i feel as if someone is stabbing me in the heart (a very sharp pain). my chest pain sometimes feel as if its heartburn, but much more serious. when i get the chest pain my heart beats very rapidly.
