It won't heal immediately even if you nurse it all day. If you want to be active on it, it will hurt and it will take longer to heal. Depending on the extent on the injury, you usually end up worsening it. You can still exercise but you may need to change the types of exercises you do. I broke almost all of my toes at different times from different things/people and what's best is to put a splint on it and to stay off the foot as much as possible.
