Hey, me too! Not that I'm glad you re-injured yourself, or injured yourself in the beginning.
I twisted my ankle falling on the ice about a month ago. It was starting to feel fine these past few weeks (unless I bent it a certain way, then it hurt a bit), and then today I went sledding. I tried standing up on the sled like a snowboard going down the hill. The first few times were fine (success!) but the very last time I did it, at the top of the hill the sled slipped out from under me and I hurt the same ankle again.
Guess I'll have to wear a brace on it and be more careful with it than I thought. Or maybe I just shouldn't be standing on sleds.
