Thanks for writing in.
From what you have written, I comprehend that you had a fall your bathroom and this led to a bump on your forehead. You also had a black out and nausea and it is hurting.
Please confirm if you had any vomiting
, loss of consciousness
, blurred vision
, significant loss of memory and disorientation
of time, place and person. If any of the above have occurred, you must see a neurologist
as early as possible. They qill advise you a CT scan of brain if required.
If nothing has occurred even after 24 hours of your injury, thaen most probably everythig is alright.
Hope this helps.
