2 year bump, very similar situation happened to me, no need to make my own thread with more questions.
It was -17 C at whistler yesterday, and I didn't realize I had my boots too tight and had cut off circulation until too late. Toes went numb within the first hour, didn't thaw until about an hour after I finished skiing (frozen for like 6-7 hours?). Right now, I still can't feel my little toe or the tip of my big toe, and my big toe has a black/blue area where the feeling is completely gone still. The rest of my toes are kinda tingly still. They're pretty swollen as well. The skin isn't white or stiff though. Sound like frostbite? Or just some mild nerve damage that should come back?
And I know, I should see a doc. But as skiers, I'm sure this has happened to quite a few of you, and nothing is better than firsthand experience. Good to know what kind of questions to ask the doc as well.
