Hesitate to post, since this was a different injury, but may have enough similarities to be useful. You might ask the doctor to compare recovery for your injury to recovery for mine.
I messed up all the outside ligaments in my left ankle 2 years ago, coming down from Superstition 5057. It was 2 total tears and 1 partial tear (almost 3 for 3!), which is bad enough for the doctors have said I might as well have broken my foot. If I look at my triplog history, the incident was 1/28/2012. I didn't have the surgery until a month after the incident, due to scheduling. I think it was 3/5, more or less. It looks like I was hobbling around the gilbert riparian preserve, on crutches, by 4/1, which means I could probably use the foot for balance (say 20 lbs of pressure). 4/15 I went to the Desert Botanical Garden, and I remember that being in the boot but not on crutches. 4/23 I walked up and down the Scottsdale Greenbelt in an ankle brace, and I remember by mile 7, I was starting to limp, by mile 8, I was starting to think I really should call someone to take me back to my car, and 11 (the end) thinking, that was stupid. My first 'hike' was 5/6, the javelina ridgeline beverly loop on south mountain, and I did it without the brace. It looks like 5/19 I was back to what I would call easy, moderately cautious hiking on 5/19, the goldmine trail in san tan park. 6/5 I was able to do Pyramid on South Mountain, carefully, and then it was slow but steady progress from there. Honestly, I don't think I could hike without keeping my ankle in mind a little for about a year. The doctors told me it would take 6 months to be mostly there, and a year to be all the way; they were exactly right. I should also note I believe I started physical therapy early/middle of April, and went for a month. I actually met hazer suzaz at physical therapy; you think you have it bad, look up her injury history (its fitting that ive met hazers 2 places: on the trail, and in physical therapy).
I think my recovery went pretty well, and I think it was specifically helped by one major thing: I had to get outside, so I did, just on crutches; then walking with the boot. It wasn't the Superstitions, but the riparian preserve was at least something. Getting outside and getting some form of aerobic exercise is very important.
Also let me say again, what the doctors estimated about my recovery turned out to be on the money. These injuries are routine for them; they know whats up.
You injured your left ankle, also, correct? Car with an automatic? For my case, I was able to start driving a week after the incident, just had to be super careful getting in and out of the car. Might be helpful if you elaborate on what specifically is keeping you from driving.
