In brief: Floats SIJ

Back pain relieved by a pillow between the legs while sleeping on the side suggests problem of the sacroiliac joint.
Between 13 ; 30% of chronic low back pain arises from this joint when it is injured and hypermobile. The pillow stabilizes and floats the uppermost sij, thereby relieving mechanical stress on ligaments that hold this joint together.
