After a game of badminton, I immediately went to pee and suddenly I felt dizzy. After few seconds I realized I fainted. There were seconds of memory loss but when I realized I was lying on the floor I immediately stood up and become normal. I had CT scan after and the results are clear and was OK. What bothers me now is my left ringing ear and my head slightly heavy. Parts of the head that bumped are still quite achy. So what am I feeling now is normal and will soon pass? What about the bothersome ringing ear?
