My “skier’s thumb” happened while playing football. A really great sport if you don’t like body parts like thumbs and knees. The problem was that with skiing following immediately on the football season, my thumbs (and fingers) did not have much chance to heal.
I should note that the current handgrips on poles are far superior to anything from years ago. Now I seldom have significant new problems with the hands. Just the old osteoarthritis blues.
CalG: Time should heal this problem, provided that you let it heal before you go out and rack it up again. Don’t do what I did below!!!
True story: I caught my right little finger in a helmet facemask while playing high school football. I was flagged for face masking and nearly thrown out of the game when I wouldn’t let go (the finger was trapped under the mask, broken backwards. Letting go would have meant loosing the finger). The trainer had to unscrew the mask to get my finger out. He then pulled my finger straight and placed it in a card stock paper splint. He wrapped it in athletic tape and I played every game and practice for the remainder of the season. Damn that hurt!!! For years I had a 45-degree bend in the finger at the broken joint. You have to love the coaching staff for their care and concern!!!
