thanks :) and normal migraine medicine usually works for about 20-30 minutes...then it comes back. thats the part that bothers me... and i was unconcious after hitting my head. but not for a really long amout of time. my sister said i layed there for a while and just moved around. so i dont know about that. but, thanks for your input. it really helps. :)
First of all, don't panic about the bump on your head :) Its normal. Most people naturally have bumps on their heads, along with indentations, from the skull fusing itself together and hardending. I don't think there is anything that can be done about an old indentation, though. Doctors would have probably fixed the problem if it would have affected you.
And you would know if something did happen when you hit your head. There would have been unconciousness, memory loss, confusion, possibly even slurred speech. Since you didn't mention any of these, I'm going to guess they didn't happen to you, and that you turned out all right after hitting your head.
For the migraines, take Excendrine Migraine. That stuff is like Jesus in a bottle, I swear. Also, try an ice pack sometimes, and lay down in your room with the lights off. A small nap can do wonders.
If it really starts to concern you, talk to your doctor.
