Hi, Thanks for using HCM.
With history of head injury
later nausea and dizziness
, You need to consult doctor
immediately. There are possibilities of intracranial bleed resulting in drowsiness
. You need to get CT scan of head to know any fracture or bleed and for further management.
Small bleed just needs observation, any ongoing bleed or large clot if formed needs immediate intervention by a neurosurgeon.
Hope this helps you.
