Depends: If you blacked out and have possible concussion, it is recommended to monitor you for any changes in your mentation every 2 hours for the next 24 hours. If you just bumped head without losing consciousness, make sure that you are not having visual issues or nausea for about 3-4 hours. If you are concerned, seek medical attention (better safe than sorry).
