Has anyone had the experience of having x-rays that did not reveal sacral fractures and then after I insisted the pain was severe an MRI revealed four sacral fractures. I am also experience lumbar pain and the doctor said the x-rays are negative. I am thinking that one needs to have an MRI to diagnose lumbar fractures also. It is so frustrating to have to insist on an MRI when the orthopedic surgeon should know that this is indicated. Thank you
