I skied for years before I tried boarding in the early 2000's. I picked it up fairly quickly but I had my bruises along the way.
The one that remains a clear memory is the slam on the cat track. I was flat basing to keep up speed through a flat part - at this point I could barely link turns. I caught a front edge and violently slammed on a ice patch. I layed there for what seemed like an eternity just trying to catch my breath! I couldn't sleep or put a Tshirt on by myself for weeks. I was broke back then and did not have insurance so I never went in, pretty sure I atleast cracked my ribs. Maybe a slight concussion too.
Fast forward a couple weeks and I back out there trying again. I picked it up and progressed from there! I do recommend lessons, I think that would of made my first few weeks easier. My buddies took me up the chair after a 10 min lesson on skating from them. They basically said good luck, cya in the bar around noon!
Only one of those buddies still rides and keeps up with me! Cheesy as it is... No pain no gain!
I seem to get worse injuries now than I did learning, I don't wreck very often but when I do it's usually painful. Last year I was reminded to scope out cliffs before you huck your body off them! I followed a line and had a bad time.
