My sister just dealt with getting one removed that had been installed incorrectly. She had intense pain and heavy bleeding for a month, during which time her doctor said she was fine, then after 6 months she was in incredible, unbearable pain. No one seemed to diagnose her properly - she thought the whole time it was probably the IUD. Finally they did an ultrasound which showed the IUD punctured her uteris. 2 weeks later, they finally did the surgery to remove the thing. Horrible ordeal. Though she doesn't need birth control anymore.
