My Daughter Went Through Rabdo Twice And Now She Suffers

My daughter went through rabdo twice and now she suffers from chronic leg pain she can't run and if walks for a long period at a time she suffers with leg pain we have seen several different Drs and they can't give us an answer they stopped her from playing ball. She is so upset, so disappointed she thinks she won't be able to play softball ever. What can we do to overcome this.
