When you lean forward and lay down and your head hurts even more, can this be a migraine? also sometimes tylenol (acetaminophen) doesn't work

You're too young: Sorry, but you do have to be 16 to ask questions here - try to have an older family member or friend ask for you in the future. But - regarding the headache you describe, no - it's not the classic migraine. Here's a description: http://www.health.com/health/gallery/0,,20537878,00.html See you when you grow up! Hope this helps.
