My 8 year old dd fell off a roundabout at the play park and then was hit in the head as it continued round. It was a nasty knock and she cried a lot but recovered reasonably quickly and appeared fine afterwards. This was a few hours ago. She says she has a headache but just where the knock was. I have asked her about sickness and vision and tiredness and then she develops a mild symptom at the suggestion of it so I am not taking these too seriously. Should I be getting her checked out or is it enough just to keep an eye on her? We are away from home but returning tonight. Any thoughts? Thanks
