I have had two surgeries where they broke my pelvis to re-align the hip socket. The second surgery didn't fix it either and so he took the screws out so they could do a 3d cat scan.... Any-hoo long story short, taking the screws out gave me some relief, but also made my leg hurt in a different way now too. I would say it is worth a try since she dosen't need the screws anymore, and as long as she is healed and there is nothing new on the x-rays the screws really could be the cause. It was a very easy surgery for me compared to the others of course, and very little down time. I think about a week...Then I was back at the gym. Good luck. I hope she feels better soon.
