The doctor said I should not just sit with my leg propped up, I should move about but keep some weight off the right knee. Well, the storm door and I are having problems. I've put the crutch on my sandal and tried to move, the crutch gets caught by the door, and I couldn't carry anything that didn't fit in my pockets.
So the thing that props the door open is helpful and so is a plastic bag with a handle. I can put a bottle of water or whatever in the bag, loop it over my wrist, put my hand on the crutch, and creep along.
