I've broken my ankle much like you did (on Mount Rainier), sprained another very badly, broken a foot and so on. It's all part of what we enjoy doing I guess.
When I broke mine I walked around for 11 days pretty much knowing it was broken but wanting to avoid crutches (and not having another trip immediately ahead) so I just waited till I got home and like you eventually did, I ended up in an air cast.
And I enjoyed reading your trip report! Sounds like you picked the right season - fall I think for your trip!
I sure hope your line of accidents doesn't slow you down too much. I try to be safe, but there is this dutch saying,
"An accident sits in a small corner"
and so these things happen. The key thing of course is that accidents in remote places can have much more serious consequences than slipping, say, on the pavement in Amsterdam ...
When I first got to the GP in Braemar, he couldn't tell the extent of the damage because of the swelling. I stayed there for two days, resting and wishing the swelling to go down. Didn't work. The doc made a house call, wasn't too happy with what he saw and sent me to the hospital.
I wasn't even sure it was broken until then, I was more thinking along the lines of serious ligament damage. I couldn't really walk, let alone for 11 days, I could just hobble. And did so, until the doc told me not to.
Apart from a little mishap on a campground a long, long time ago, this is the only time I've had a cast, and I hope it's going to be the last. It will serve as a good reminder to be careful even on 'easy' terrain.
Oh, by the way, about the seasons? The aborted trip to Scotland was in spring, the Alps in summer and Bolivia in late winter. From what I had read, June thru August are the best months for mountaineering there, but May and September are not too bad either. And the good thing about September is that it's not as cold as mid winter. But the real reason I went late in the season, was that I wanted to spend some time with my friends first and we agreed on early August for the Alps. I like going out with my band of mountaineering friends, Bolivia would have to wait a little :)
"So I was sitting in my cubicle today, and I realized, ever since I started working, every single day of my life has been worse than the day before it. So that means that every single day that you see me, that's on the worst day of my life."
