Hi,
Thank you for posting your query.
I have noted your son's symptoms, and I would like to reassure you that based on the symptoms, he does not seem to have suffered a serious
head injury.
Please watch for symptoms such as
severe headache,
drowsiness, vomiting,
double vision, fits, weakness of one half of body, etc. If any of these develop, then, you should call 911 and take him to emergency.
As of now, you can give him ibuprofen for headache and
betahistine tablets for dizziness.
I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.
Wishing you good health,
Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)
