Waking up with really bad head aches?

A couple weeks ago i got into a fight, this crazy chick punched the back of my head consistently. and the next morning i had like 3 goose eggs on the back of my head. Ever since then i've been waking up in the morning with REALLY bad head aches, taking 2 extra strength advils barely seems to help. and the head aches usually last all day. i dont have any bruises left on my head or bumps so i dont know why im getting these bad head aches.
