Preventing arthritis after fracture

I was in a car accident on June 1st resulting in multiple fractures the largest being located in my pelvis. I fractured my acetabulum and sacrum bone both on the right side. I'm on crutches now with strict orders not to put any weight on my right leg. I'm 24 years old and led a very active lifestyle before the accident. I hope to recover fully arthritis-free, but lately I've been concerned about pain that I've been feeling when I move my right leg at the hip or bend from the waist. Should I be worried, or is this normal? Is it possible that I am moving around too much?
