A bad sprain can take weeks to heal. I would still expect there to be bruising but it should be reducing now and not still coming out. If it is a bad sprain she really needs to be using it as much as she can to make sure the healing process is as quick as possible. If it has not been checked over by the hospital it might be worth a visit, however if it is a few weeks it is highly unlikely that they would cast it or anything, they may splint it but not crutches for a sprain.

Smal circular flexing exercises are helpful as are up and down on tip toes, as well as light tapping of the foot on the floor.
