Got hit on the head with basketball but i don't have any other symptoms. could this be a concussion?

No: If you did not pass out - then it was not a concussion.

Probably not: A concussion involves either loss of awareness or possibly altered mentation, so potentially things like confusion even in absence of loss of consciousness can still be a concussion. Without any symptoms, however, it probably wasnt a concussion.

No: It doesn't sound like you are describing any symptoms of a concussion.
