i'm 12 and for a the past few days i've felt a little weird cause i was getting headaches regularly, and i've only had about 10 in my life, but yesterday when i was in the woods playing with my friend i slipped and landed on my butt ( which hurt cause i landed on a rock ><) but when i got back up and started laughing i got really dizzy and felt like i was going to throw up and i had to lie down on a log for a few minutes until i could drink some water. the headaches havent gone away and i'm still kinda dizzy. this is really freaking me out and i dont want it to happen in school, does anyone know if this is normal and if it isn't what's wrong with me?
