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.
