Thank you for posting your query.
At present, there is no need to worry, as your symptoms suggest only a mild head injury
. There is no symptom to suggest internal brain injury
The swelling is likely to be due to scalp hematoma (bleeding underneath the skin over head).
If you develop severe headache
, double vision
, recurrent vomiting, fits, etc; you should go to ER and get a CT scan of head done, otherwise, continue to observe at home.
