claflamme

I have a question about leg descreptiency. I ahve a 2yr old daughter,almost 3. And since she was about a yr old maybe 4 times total she would be fine just walking along and just stop and lift her right leg a bit and start screaming in pain (she didn't step on anything) but as if it were coming from her hip. It happened 2X between the ages of 12 months-18 months or so. And 2X a few weeks ago. We just noticed that her right leg is about 1/2"-1 inch shorter than her left leg. She does walk with a little limp and she falls alot. Her ped refered her to an orthopedic dr. Could the descreptiency be causing the hip pain? And how do you fix that,maybe a lift in her shoe?
Any thoughts are greatly welcomed.
Thank You
