ok about a week ago i jumped in my bed to lay down,when i landed i felt this pain near my heart so i got up and went to my moms for comfort,grasping my chest all week i been having this faint pain near my heart but only when i move in certain positions,i do not feel it now but i i layed on my side i might feel it, i have layed flat on my stomach and not felt a thing i doesnt hurt when i breathe or anything,but there is this really faint pain that just comes whenever i get in a certain position, sometimes i l punch the air 50 times really fast just to speed my heart and see if it hurts,but it never hurts,only when i lay down in a certain position. i am going to the docs monday to get a checkup
