Update 5/21/12:
Thanks Pelove and eits for the suggestion of ice packs! This has been a great relief. The first day after applying it the night before I could tell things 'settled in' much better. It still has a weakness for moving wrong and will need to firm up some more, but it feels that everything is in the right place. In other words, while it's not perfect, it doesn't feel nearly as vulnerable to re-injury as it used to. I've iced it every day since, including after every workout, and will continue to do so until it no longer feels beneficial.
Thanks everyone for your feedback!
