Hello~I would not worry. CT scans can show if there is swelling or bleeding in the brain or a fracture in the skull. If you have signs of a serious injury, a CT scan is usually the best first test to diagnose it.
As to the concussion being permanent, in most cases, a single concussion should not cause permanent damage.
Thanks for the reply. Will the symptoms of a concusaion go away maam?
Thanks. Should i get another CT scan of the head to be sure there isnt any internal bleeding or a crack in the skull? Or was the first CT scan accurate? Im worried that the first CT scan wasnt finding anything because the ct scan was a couple of hours after the injury and there was too much inflammation that they couldnt see internal bleeding or a crack in the skull?
