i had pins plced inside my hips when i was 13 years old, and i can not remember what type of surgery it was i had. the thing was that when i walked i i would walk side to side like a duck, and then it would hurt as i walked,even when i would stop to take a rest, my hips would throb with pain. all i can remember the doctor telling me that, my upper part of my body was growing faster than the lower part of my body? what is that called in medical terms?
