typically, you can start back with drills with one leg raised 9injured leg down- so A skip would have the opposite knee coming up. After a day or two you can do two legged drills with low knees- I cover much of this in the CFTS manual- it lays out a ten day rehab.
I think you have it don’t you?
BTW, hearing you getting out your tempera and oils makes me think of my father. I’m hoping to post some of his paintings. I’m hopeless at computers as you can tell but someone here may be able to make a file for me to put up. he was a painter and sculptor.
