What grade concussion did i sustain when 11? i dont remember from an hour prior til 5 hours later, told no loc, told coherent in er.

Grade 2-3: The duration of your concussion would be considered a Grade 2 to 3. You do not need loss of consciousness to have symptoms of a concussion The 1 hour prior to the concussion may fill in, but do not expect to gain memory of the 5 hours after. I hope you are feeling well now. Be careful because after one concussion it is somewhat easier to experience another.
