Why does my head and jaw have sharp pains every once in a while?

every once in while eather my jaw or my head hurts for like 8 seconds! HELP!

Can you explain the pain behind it, where it hurts, what you're doing when it hurts, or something that you had done to your head/jaw that could've caused an injury?

You could've banged it, you could have some minor brain damage, or simply pressure building up inside your skull.

Maybe they are just "Growing Pains" I get them in my arm every once in a while.

maybe cuz you did some thing to your head
