In April, DD sprained her ankle after she slipped over at school. It was a pretty severe sprain and she was on crutches for a week, and it was still swollen and occasionally painful for months after. On Monday, she fell off the side of a path walking home, and sprained it again. It wasn't as bad and she has been walking on it (she says it is still painful, but she has had to walk on it as she has work experience). It's swollen and bruised today (Thursday), but she says that it's less painful, and not as bad as before.
My question is will she have any lasting effects? Before this sprain it was swollen and painful, so would it be worse now? Is there anything I can do to help her, such as getting her an ankle support or suggesting some exercises to help strengthen it? (She wants to be a teacher and she'll obviously have to be on her feet all day, and I obviously don't want her to be in pain).
