There was no such feeling before. Two days ago, I was hit by a car and my head was wrapped around the earth's brain. CT showed that it was good to sit in a normal hospital for four days. I just lay down and didn't dare to move. When my neck tilted back to a certain angle, I would feel that my neck can't support my head. When I lay down, I need to be on the side to suffer from leg bone fracture. Now I have conservative treatment at home for four days

Considering that the sequelae of mild concussion causes dizziness, neck discomfort and lack of rest, you should go to the hospital to check whether there is cervical injury if necessary. At present, we mainly pay attention to rest and don't catch a cold.
