I deally, you would have been doing rehab exercises early on, like passive range of motion (moving your ankle with your hand) and then active range of motion (moving your ankle with your ankle muscles.) And then resisted motion (like against rubber tubing). You can still do these.
Try walking before you try running. Ice it if it hurts afterward.
Practice standing in crane stance. If you want to make it more challenging, do it on a rocker-board (or wobble-board). Check a physical therapy supply place for these.
