About 8 months ago I had a very serious surgery that left 4 screws in my pelvis and 4 screws in my femur and a rod in my femur, my leg was broken in 3 places and my pelvic ring was broken. I am pretty much fully recovered but I still find it hard to walk fast and for long periods of time, my knee starts to hurt. I was thinking taking the screws and rods out of my leg would help me walk better. How long do they have to stay in before I can have them taken out? I was told 2 years but I dont want them in that long so I am looking for a second opinion.
