Ankle pain constantly for over about 2 months

Hi,
my daughter has had a lot of ankle pain over the last 2 months. She has complained to me about it hurting on the right outside of her ankle every time she walks and even when she sits or lays down. She has tripped and fallen before, but never very hard. She is a very active 12 year old and regularly(just not recently) competes in figure skating and does gymnastics. We have tried wraps and even crutches, but the pain wont go away. We have seen several doctors and we insist of xrays but they just don’t give them to us and they insist she is fine. Do you have any thoughts of what we should do?
