I am not sure how quickly you are back to work and on your. This summer I severly broke my big toe, not doing tree work, but helping a friend remodle his basement. I was in a hard cast and crutches for a month, and a walking cast for another 3 weeks. Luckly my job didnt require climbing trees, it would have been hard with crutches!! I was working with oak wilt all summer and able to get by with a cast.
Two summers ago I was helping the same friend by doing some tree work, and steped in a ground hive of bees. I ended up getting stung about 30 times. Needless to say I have had some bad luck at my friends house, and havent volunteered to help him with any projects recently.
So anyways, I hope your toe and your back are both doing better.
