so i ended up skiing about 5 times or so with the cast. There was one time when I fell when my thumb began to hurt. Didn't think it was to big of a deal, and the pain was gone within a day or too. Few weeks later...Today I got my cast off, and as soon as I looked at my thumb I knew something wasn't right. Turns out I must have re-broke it when I fell, causing it to heal in a odd position. Looking at my thumb the bone sticks out creating a big bump, and giving me limited movement. Because of this I will have to get surgery and my ski season is over :(
Morrow of the story is to listen to your doctor. I felt that because I had a hard fiberglass cast, that I would be protected and there was no way I could mess up my thumb anymore. Now I have to have surgery and miss the rest of the season.
This isn't made for you to feel sorry for me, but instead, be smart about your injuries.
You're going no poles now.
