With a broken leg and a broken car. On the way, the car suddenly broke down. What should I do if my leg is injured? Good thing I have crutches in the trunk of my car. Having put on a boot on the injured leg and taking crutches, I return home, but the boot squeezed the injured leg so much that the pain was unbearable. Taking off my boot and throwing it right on the road, I continued on my way in one shoe.
