Sigh...I'm married to one, so I feel can say this: please take the time off to rehab right so you don't have long-term ankle issues. My husband was probably a senior captain before he dealt with his weak ankles that were a legacy of four years of just lacing up the rocket socks and running just because there was a race, and he was young and invincible. After graduating, he used to turn an ankle just looking at a rock. It was silly. Especially for an infantryman.
Visited physical therapy people. Roads are fine. My ankle loosens up as I run on flat surfaces so that's good. Ibuprofen and range of motion stretching will smooth things over for Boston.
After that, I'll take trails with a huge grain of salt.
:-). At least you're thinking about it. Run well!
