Being knocked unconscious?

[Kaiserschlact 1918]

When I was about 5 or 6 I sprinted into a car side-view mirror and was knocked unconscious for about 5 minutes; I was taken to the emergency room afterwards where I was told that I had not had a concussion. Does anyone see this as being a problem for my medical?

Not unless you're still unconscious....
