The Anatomy of Sacrum Pain: Symptoms & Treatment

When people refer to sacrum pain, they are usually talking about pain that affects the sacroiliac (SI) joint in the spine. The sacrum is a triangular bone at the very bottom of the spine, formed by five fused vertebrae. On either side of the sacrum are two wing-like bones that join via strong ligaments with the iliac bones of the pelvis. Unlike the other vertebrae of the spine that are connected by flexible discs, the sacrum itself and the SI joint have very little motion and flexibility. Instead, their primary roles are to support the spine and absorb shock.

Sacrum Pain Symptoms

Just like the other joints in the body, the SI joint can degenerate over time. The ligaments around the joint can stiffen, or they can develop tears and loosen the joint too much. Either scenario can cause the joint cartilage to wear away, leading to the sacral and iliac bones rubbing together and causing pain. This is also a synovial joint, which means it is filled with a lubricant called synovial fluid. Over time, the synovial fluid may become inflamed and cause further discomfort.

Sacrum pain caused by SI joint dysfunction can take many forms. Symptoms can include:

Groin pain
Muscle weakness in the legs
Pain in the lower back
Pain when moving standing after sitting for a long period of time
Pain when standing for long periods of time
Radiating pain in the hips, buttocks, and legs
Tingling or pins-and-needles sensations in the lower extremities
