Can someone go swimming if they are recovering from torn ligaments in the foot?

I got into a mild accident last week; after being checked out, i don't have anything broken but i have torn ligaments in one of my feet. My recovery has mostly been resting my foot and not putting pressure on; i'm not allowed to go for a walk. Would I be able to go swimming? This way I can keep my foot from being stiff but i can do some exercise.
