Alva 61 Sprain - I think my foot is even more swollen now - 5 min

Alva has just re-injured her ankle and jumps on one leg to pick up the crutches she put away.
She crutch out from the schoolyard and further down towards the parking lot where the car is parked.
How could this day that started so well end with her now again probably having to use crutches for several weeks and have pain in a now more swollen foot?
