Hi, My Son And Daughter Were Playing About 4 Weeks

Hi, my son and daughter were playing about 4 weeks ago and a small but heavy coffee table landed on my daughters foot, she is only 2 and her foot got trapped under the table, I quickly removed it when I heard her screaming and I noticed her foot had swollen and bruised, and it was in a lot of pain, its the top part of her foot, anyway we took her strait to the hospital and after 4 hours of waiting they basically sent us home, 4 week have gone and she's walking fine on it but the bruising is still there and its still quite swollen, what could she have done?
