A: \u00a0Why is my sacroiliac joint pain worse at night?<\/strong><\/p>\n

The sacroiliac (SI) joint is the joint that connects the hip bone with the sacrum at the base of the spinal column and lies between the large bones of the pelvis. (The pelvis is the group of bones that connects the trunk and the legs.) The SI joint is the largest joint in the body. Strong ligaments around the joint help stabilize it, supporting the weight of the upper body and transferring the load between the spine and the legs. Because its primary function is stability, it\u2019s a very stiff joint and has minimal ability to move. About 15 to 30% of low back pain can be attributed to dysfunction of the SI joint.<\/p>\n

Your SI joint can be injured or degenerate as you age and cause low back or spine, pelvic, leg, or buttock pain.<\/p>\n
