Hey its been awhile since i posted anything but have a few new questions to ask. occassionally i get this thing where my heart starts racing really fast and it beats extremely hard to the point where it shakes my whole body if im leaning against anything. i also white out get very light headed have shortness or breath and sometimes pass out. i have no idea if this is related to the concussion or not but it never happened before i got it so im confused.

does anyone else get this ever or does anyone know what it could be it get me kinda worried when it happens and i dont want to pass out at practice again or its back to the doctor and no more basketball. anyone have any idea what this could be?
