Black and white after falling?

Hello a few years back I was playing soccer in P. E and fell on my wrist. As I got up, I noticed that my vision was actually black and white, had difficulty hearing too plus had some dizziness. I had to sit down for a about 5 minutes before these issues faded. What really concerned me was the vision and hearing issues. I kind of shrugged it off but it has always been something I was curious what exactly happened but never got an answer for. It's odd too that these issues happened after falling on my wrist and not my head. I have no medical conditions either. I asked my family doctor shortly after too and they shrugged it off as well so I never bothered looking into it more. Has anyone experienced this or heard of this before? It only happened that one time too. I'm sorry for the wall of text too, I'm on my iphone so it isn't the easiest thing to type with haha.

Some people have had falls and don't remember hitting there heads, where in they did, and they had a slight concussion, seems like the only simple answer.
