bump in the head if not accompanied by any unconsciousness
or dizzines or ringing in the ear or vomiting
is nothing to worry about. topical NSAIDs with some rest and even oral acetaminophen
will be enough. if there is a wound , you need to care for it.
if there are any of the above symptoms, have your vestibular exam and Ct brain with an ecg to be on the safer road.
