Ankle Sprain

I have sprained my ankles many times mostly my right leg’s ankle.

About two months ago sprained I sprained it again and since then it has had a bruise on it just little spot on it about 1,5cm(0,6inch) in diameter. What would you suggest me to do to get it back as strong as it was?

The truth it will never be as strong as it was but i’d like to believe it’s possible.
