Hi,
Thank you for posting your query.
The current symptoms suggest a mild
head injury and a scalp hematoma (bleeding underneath the skin).
Headache, dizziness and vomiting are part of that. Partly, the symptoms could be contributed by his flu.
Please continue the symptomatic treatment such as
diclofenac or ibuprofen for headache,
ondansetron for vomiting and
betahistine for dizziness. We expect him to get better in a few days.
However, if he does not recover or if his symptoms worsen, you could take him to the doctor.
Best wishes,
Dr Sudhir Kumar MD DM (Neurology)
