thanks for the question
It is advisable to take him to a neurosurgeon at the earliest and get a CT scan
done to rule out any intra cranial hemmorhage (bleed) for which he will need immediate treatment depending on the amount of bleed .
there is also a possibility of it being a minor concussion
meaning a mild head injury
without any intra cranial findings . But it can be confirmed only by a Ct scan .
In case its absolutely not possible for you to meet a doctor then look out for the following danger signs ......
1. any loss of consciousness
3.bleeding through the ear , nose .
4. not oriented to time , place or person
5. not responding to commands
6. any neurological deficit like unable to move his limbs
7. periods of amnesia
8. convulsions (fits)
In case of any of these take him to a neurosurgeon immediately
