First, realize that a sprain means that you stretched out the tendons in your ankle beyond their normal range of motion. In all but the most extreme cases, this means that you did little to no long-term damage to your tendon. Obviously there are exceptions to this, and you may fit in that category.
That being said, your approach to healing should threefold:
1) Use ice, advil/motrin (if healthy enough), to decrease inflammation
2) Work on increasing range of motion
3) Build strength in the surrounding muscles
For range of motion, try sitting down with your foot up off ground and drawing the alphabet with your big toe. Make sure to full stretch for each letter.
To build and test strength, alternate standing on your tip toes of the effected leg, building up to doing so on a stair.
Once you can do all of that above with only a bearable of even minor amount of pain, than start with more serious excercises.
Also, in terms of burning calories in the meantime, there are much more effective ways to burn fat than low intensity cardio. Try push-ups, ab excercises, or other weight lifting as they are more effective.
