What can i do for my concussion without going to a doctor?

I am not sure?: How did diagnose you that you have concussion? Did you diagnose your self? What if you have brain damage? What if have subdural hematoma, i think you should see the doctor.

Depends: The effects of concussions can vary and be unpredictable. It depends on the severity of the injury. The symptoms can include headache, dizziness, vision change (blurred vision/ double vision), nausea/vomiting. If your symptoms or headache are severe, or if you have a loss of consciousness, you should get evaluated immediately.
