A swollen ankle is the least of your problems. Maybe you should work on perfecting the death-defying art of sitting down without severe personal injury. I'm sure there are safe sitting coaches who will come to your place and show you the esoteric craft of chair-using.

I also recently got a 3rd degree sprain on my ankle, it was the size of a baseball. 4 weeks in and I am still struggling to stand on my foot for more then 2 hours at work, and have to continue to wear my splint. I'm off of my crutches though! remember to elevate and ice your foot, when you feel comfortable to move it some, write the ABC's with your ankle. I'm sorry about your injury
