What Causes Walking Difficulty Along With Back Pain With A History Of Fractured Sacrum?

5 years ago I slipped on a waxed floor and sustained an oblique stable fracture of my sacrum. Since then I have found it difficult to stand from an crouching position, I have discomfort when making a step up and after sitting for any length of time I have pain across my lower back at the level of my hips. Is this the result of my injury?
