My daughter fell yesterday and her ankle became very swollen and bruised. We took her in to urgent care and the dr. said xray showed possible hairline fracture. He had a radiologist look at it and called back today and said no fracture, just bad sprain. Do I need to take her for a follow up with an ortho dr.? If not, should she remain on crutches and in her black boot for now? How long? Should she try to walk on it? When? Thank you for your help!
