Sarah's knees

Took Sarah to the an orthopedic doctor today, I'm not sure what he said the official problem is, but he did say it's normal for girls her age to have the pain and swelling problems she has been having. He is going to have her do physical therapy and she her back in 2 months. I hope the PT helps her, she's been sitting out of her dance classes for 2 weeks now. And not doing PE in school.I asked about using a brace during exercise and dance, the doctor said we could try if we wanted but it usually causing itching and it gets abandoned. She wanted to try it though, she knows how much her knees hurt. I bought one to start with to see if she likes it. No sense in wasting another $15 if she won't be using them.
