We have just been to the local fair and my son and I were in a ride, fast and loud. They turned the lights out towards the end and put in strobe lighting and a smoke machine. My son was singing, cheering and giggling. Next thing I know he went limp and his head went off to one side. I shouted his name, shook his arm (wasn't sure if he was pulling my leg) then after a couple of seconds he came back and didn't know anything had happened. He has never had anything like this before and is a fit and healthy 9 year old. Should I be worried, get him booked in to see the doctor etc?
Thanks in advance
