I say you should tape your ankles when you run like american football players do. right over top of the shoe. If you keep "twisting" your ankles you will pull or tear ligaments and they can take a long time to heal and one more twist and its hurt again for a long time. i hurt one while skiing and it took like 2 years to completely heal. but i was old like 35.
Preventing it from happening is the most important thing. and rest to let it heal before you try and strengthen it. if you try and work it now youll do more harm than good. You body grows at differnt rates and places. be patient. i assume your a kid. relax,
