hello and thanks for the query.
I understand your concern since your child is hurt.
 A prompt cry after the injury is reassuring. It is normal for a child to feel sleepy after hitting her head, and is even O.K. for her to vomit once or twice and having some headache. The following is a list of signals that tell you that you need to talk with your pediatrician. If your child is (or has):

Unconscious, even briefly
Crying for longer than 10 minutes or prolonged irritability
Vomiting repeatedly
Bleeding or other liquid draining from the ears, mouth, or nose
Rapid swelling just above the ear
Bruising around the ear or eye
Unable to walk or talk normally
Acting strangely or drowsy
Unequal pupil size
Severe, worsening headache
Neck pain or stiffness
Seizures
Skull indentation or large bump
Great force of injury (car accident, long fall, baseball bat, etc.)

If any of these symptoms or situations are present or if you have any concerns, call your physician right away.

If none of these symptoms are present, it is fine with her and just wait and watch her.Every thing should become alright soon.
You can give some Tylenol for the headache.
I hope to have answered your query however you can revert to me for any other query.
Thanks and best of luck.
