Took a tumble a month ago. Late Saturday at Sugar, NC. Light was flat. I hit some bumps in the snow, medium speed. Board went out from underneath me, and I landed on my head and shoulder. As my body caught up, I heard what sounded like a crunching sounds coming from my chest.
Had to sit down for a couple of minutes after that, and felt a little nauseous. It passed. No double vision. Rode down to the bottom. The helmet did it's job. Pain subsided from my shoulder down after a while and migrated over to the chest area.
That day was quite an adventure; the snow was making the race course very rutted, and several folks were hauled down the slope with damage. Our race captain (skier) trashed his ACL that day and is out for the season.
I was contemplating taking the next day off, but as so many others had been damaged worse, I put in my race runs, and did a little free-riding; keeping things conservative.
My chest area on the right side was quite painful for a few days, especially to sleep on. I'm guessing bruised ribs. It was somewhat painful for a couple of weeks. Today, just over a month later, I can still tell, but the pain is now barely noticeable, and only apparent when I move in an unusual way.
Anyhow, that's the first injury snowboarding in a long time.
