On Saturday I attempted an arched rail, but slipped sideways and fell. The back of my head smacked the rail and I was on the ground. Weird thing is that I never saw myself fall. It was just slip, slam, somehow on the ground looking up in a second. My vision went yellow for a moment and I could feel my brain swelling a little inside my skull. I guy came over and asked if he should call ski patrol but I said I thought I was ok and luckily I was, except for the headache for the rest of the day.
All this happened with my helmet on. I can't imagine what it would have been like had I not been wearing it.
The helmet itself looks fine but I don't think I can afford another at the moment if it does turn out to be cracked.
