I'm 13 and my Name is Emma, for the last few weeks i've had a pretty much constant head ache, I gtw sudden dizzy spells at the most random times but mainly if I have been sitting or lying down for a while, sometimes when I stand up everything goes black, I can't see and then I'm fine after a couple of seconds but it's still a bot blurred. No one really believes me because it's so odd, does anyone know what it could be ??
