I know this is and old question - but if your daughter is still having pains, take her to a chiropractor. I used to always get pains in my hip as a child. My mum thought I wanted to get out of school ( I guess most parents would assume this) but I didn't.  I started seeing a chiropractor after I started working, and x-rays showed that my pelvis was out of alignment.  I no longer suffer the problem.

sorry i replied to the wrong ? before. As i said does your daughter eat more? As my son does and he is having sore legs and is growing at the moment. He tends to eat more fruit and dairy products whilst he is growing more than usual anyway. I hope that helps

I had the same thing when was about two my mom said i would always say my knees hurt and the doctor said it was growing pains. And now my daughter is saying the same thing. The only thing is my "growing pains " still happen to me and they always have. But they happen alot less as i got older.

I know that dosnt help but now you know it happens to others too
