Hi, on Saturday, about 2 days ago, I was at a water park in a wave pool, in the shallow part of the pool, and one of the waves flipped me over and I banged really hard the top of head on the concrete on the bottom of the pool. I got up with a lot of pain and later on a bump formed on the top of my head. I was really tired later that evening and slept a lot. Last night I didnt sleep well and woke up twice with a dizzy feeling. In the morning, I still had the dizzy feeling and still now. Should I be worried, because its already been 2 full days that the accident happened? should I get it checked out?
