My 11-year-old son collided with another player on the soccer field about 2.5 hours ago.  Both players were dizzy for a moment when they stood up.  My son was taken off of the field.  Thirty minutes later,  my son vomitted and said that his fingers felt tingly.  His pupils are reacting to light normally, but has head hurts and he feels nauseous.  How long should we wait until he can fall asleep?  Can anything be done for a concussion, or shoud I just watch him closely?
Hello, Thank you for trusting Chat Doctor. Hope your son will get better, its important that you take him to hospital for close monitoring since he felt dizzy, and he vomited. They will probably perform a CT scan since cranial computerized tomography (CT) scan is the standard test for such cases. Please don't hesitate to Chat Doctor.  Falling asleep is not a good thing without doctors checking him. I hope this will help. Best regards,
