Hi,
Thank you for posting your query.
Based on your son's symptoms, I do not expect any significant head or internal
brain injury. So, there is no need to doing any CT or
MRI scan of his brain right now.
You can wait and watch for another 2-3 days for his
headaches to subside. If symptoms persist, then, you may take him to a doctor.
Also, please watch for symptoms such as giddiness,
vomiting,
double vision, etc, when he should be taken to the ER (less likely to occur though).
I hope it helps. Please get back if you require any additional information.
Wishing you good health,
