Question: My 8 year old son went to a baseball camp today. When I picked him up he said he had a headache which he has gotten before as he takes vyvanse. He did not take the medicine today though. As we were driving home he then told me that he was hit with a basketball in the head. He said it was not hard. Before we got home he threw up in the car. When we got home I checked his eyes and they were not dialated and he took children's aspirin and fell asleep for 45 mins. I woke home up and within 20 mins I checked his eyes which were still not dialated and he has gotten up, ate dinner and had some juice. He now told me that the ball hit him and he continued to play for a while and from what I understand his headache just got worse before I picked him up. Should I still be concerned with and brain injury? Should I still take him to the ER for a CT?

He did only vomit once when the car was moving on our way home. For the last 2 and a half hours he has been up playing watching tv and eating a full meal. He says that his head is not hurting at all. So it is still better to do the CT even at this point?
