13 year old daughter has lordosis. It isn't super noticeable, but if you actually look at it you can notice the curve right above her buttocks. We also tried doing those "tests" where she lays down and tries to see if she can fit her hand through the area where the curve is. She is able to fit almost her whole arm through that area. She hasn't complained of any pain, and I'm not sure if we should see a doctor for this or not.
