I was the victim of domestic violence two days ago. I was hit twice pretty hard on the side of my head (left ear area - open slap) both times i was knocked to the ground. Since the incident my head feels full - especially my left side - the ear it s self burns and seems to feel numb. The right side seems full as well but not as severe (no direct injury or contact). My hearing is muffled and i ve kept a slight headache. Mentally, i feel confused and very tired. Another issue is that I am cold, actually wearing a light jacket and sitting under a light blanket (no ac on) - I live in florida - the temperature outside is 84 - 85 degrees. Is it possible I have a concussion and if so how do i treat it.
