What Is Sacroiliac Joint Pain (SI Joint Pain)?

Sacroiliac joint pain (SI joint pain) is a type of chronic pain disorder caused by inflammation, stiffness, and other abnormalities in the sacroiliac joint, located where the spine meets the pelvis. The SI joint acts as a shock absorber as the body moves and takes the pressure and load off the spine. If the joint becomes over-stressed or inflamed, SI joint pain can result.
