got to the doctor
You might die.
It could be a tumor. You should get it checked out.
You have a goose egg. It happens when you smack your head on something really hard.
If someone tells you, your head is as hard as a rock it probably means your head is very hard
All the Kings horses and all the Kings men work very hard to put Kirin's head back together again.
This is a very difficult major engine repair and should only be attempted by a professional.
It is very hard to tell so you should go see a doctor to make sure it is nothing serious.
well it depends if u hit ur head very hard then probably i might wanna go to the docter if it last a month
You may have a problem with your brain. Throbbing pain in the back of the head is a sign that the back of your brain is slightly lower down your neck then it should be. I have this condition myself. It is not a problem you should be very concerned about as the only thing this problem causes is headaches.
you will have a canser and die
When you hit it very hard over the head.
it is mean to call people hard head. they cant help it. well sometime i am hard head at school. i also play softball. Actually it means you are very smart or sometimes it is used in a serious way when you hit your head very hard and you are just fine. So the comment before me really made no sense at all.
