Had same problem 2 weeks ago. When leaving hotel in Garmisch with about 40kg of stuff on my shoulders, I missed stair. I was actually working normally for all day (that included two runs with photo equipment on my back down the women SG course), but after that, I was hardly walking for next 3 or 4 days. Luckily I wasn't assigned for Val d'Isere, because I have no idea how I would be working there with this ankle.
In between I went to 3 acupuncture sessions with my physio, and this weekend I was thinking I'm fine, so I was actually planning to get some skiing yesterday. I was walking around without any pain, I could even run a bit, but when I tried to put ski boot on evening before, I was almost crying of pain when trying to put it on. So instead of alpine skiing, I got 2h of a bit painful xc skiing yesterday, and I hope it will get better till end of this week (almost 3 weeks after my "accident") when I'm at WC in Tarvisio, and I will have to be on course again.
But I guess it depends how bad everything is on beginning already. My was pretty bad.
