Concussion: You may have a concussion. They are brain traumatic injuries. Your hit on the window above your Temple is part of the skull. They are graded 1,2, 3. You sound like a Grade 2 moderate concussion. With no other red flags like vision changes, slurred speech or history of brain tumors you are doing the right treatment. If unsure seek further medical attention.
