My daughter age 14, got a concussion (mild) in PE Class yesterday by getting hit with a hand ball in the left side of her head which in turn made her hit the right side of her head on the bleachers. She got dizzy and nauseated few moments later and went to the nurse. I took her to the hospital and they said she had a mild concussion but with the headache, blurred vision, light sensitivity symptoms could last a few days. She just threw up and now I m not sure if we should go back or is this typical for someone with a concussion to go through.
