Welcome to Health care magic
I went through the history you have posted.
It seems you had a head injury
as hit head against the concrete.
Since you have taken CT scan
and this is normal I do not think there is a need for second CT.
But if you develop symptoms suggestive of head injury like vomiting
, nausea, dizziness
.... and if there was history of loss of consciousness
following injury you need to consult your doctor for further evaluation and treatment.
If you are not having any of these symptoms then no need to worry you can continue the treatment as advised by your doctor.
Do write back to me for further questions.
Thank you for writing to health care magic.
