Would a recent back injury be the cause of my hip ache?

Back and hip pain: Certainly, injury to the discs in the lumbar spine could cause referred pain the the groin area (this is the hip joint) or genitals. Pain on the side of the hip where the bone is most prominent, would likely be due to bursitis. Pain in the hip pocket region, would be likely sacroiliac or piriformis syndrome. All should improve with time, nsaid's, heat/ice, and gradual return to normal function.
