Physical therapy is an interesting thing.
Right now is the "easy" part to rebuild the basic strength - flexing and stretching to build up the muscles in the ankle and rebuild the spacial relations/memories of the nerve endings and where things should line up ... or something like that.
My set of exercises for the week include drawing the alphabet with my foot - upper or lower case, my call - a couple of times a day. I also have a red elastic thingie for resistance when I flex the ankle and stuff.
The good news, I can start going for walks of increasing lengths. For example, today I can go out for about a half mile or so and see what happens. If I'm not sore or swollen, then I can go longer tomorrow and so on.
But for now, I'll write my letters in the air with my foot three times a day while I anxiously wait for the word to run again.
