Dear Kaykayro, hello.
Thanks for writing in. Let me help you to solve your problem.
It is not necessary that every head injury
result in internal injury. Headache can be due to soft tissue injury
. You are not having following symptoms, so no need to worry:-
1. Loss of consciousness
3. Nasal/Ear bleed
5. Difficulty in walking
6. Memory loss
So you can sleep without any tension.
Hope this is helpful to you.
Thanks and take care.
