youll be ok, the seriousness of being knocked out is greater if you have been actually punched. its happened to me a few times. one second your on your feet, next second you open your eyes and your looking at the ceiling. anyway my trainer told me that it depends on the severity of the hit.
when you get hit, your brain moves inside your skull. the brian floats inside your skull on cerebrospinal fluid, you lose consiousness when the brain moves in this fluid and hits the side of the inside of the skull. depending on how hard you are hit, will result on how long you will be unconcious for.... when the brain hits the skull it shutdowns, and the harder you are hit, the longer it takes to recover...
