In looking for ideas of what may be wrong with my brother's back I came across Lordosis. From what I read the lordosis can be caused be muscles in the legs. The excercises stretch these muscles out and relieves the pain. Your daughter's imbalance is more caused by her curves. The curves through you "off center" and that causes balance issues and clumsiness. I also had sever curves before my surgery and my balance was nonexsistant! I sincerely hope that by now she is doing better and that you've gotten a second opinon. I also read that wearing a brace as well as excercises can help the pain a great deal. God bless and I will keep both of your children in my prayers!
