Did anyone ever experience this?

Years ago I was at my church, running around with my cousin. I tried to run into the bathroom, but I hit my head on a wall and saw stars.
But I wasn't knocked out or anything- just a small bruise on my forehead.
I put ice on it and it went away the next day.

Was it possible I had a minor concussion? I didn't have any symptoms.
Did anyone ever experience this?
