In December, 1994, I suffered a major concussion thanks to a bare-knuckled fist to the head. I was knocked unconscious as my head slammed against the ice, and carried off the rink. In the locker room I took multiple showers, because I kept forgetting that I had already showered. However, the team quickly cleared me to play despite signs of a serious concussion. A few weeks later, I experienced a grand mal seizure during a workout.
As I convulsed, my teammates restrained me from hurting myself any further, but the damage to my brain had already been done. Incredibly, it was a team orthopedic surgeon who treated me after my seizure. I sat out for just two weeks before the team doctors again pushed me back onto the ice. I was never seen by a neurologist.
