Thank you for posting your query.
Your symptoms are suggestive of scalp laceration with hematoma
(bleeding underneath the skin).
You are fortunate not to have suffered any internal brain injury
These symptoms would resolve over 2-3 weeks. You could take anti-inflammatory drugs such as ibuprofen
for faster recovery.
There is no need of any CT scan of brain at present.
Wishing you good health,
