Studies show that the sacroiliac (SI) joint is a source of pain in 15-30% of patients with chronic low back pain.
SI joint dysfunction can be difficult to pinpoint without proper medical diagnosis, but chief symptoms can include low back pain (below L5), pelvis and buttock pain, hip/groin/thigh pain, sensation of lower extremity pain or numbness, sitting issues, pain changing positions or transitional motions, poor sleep related to pain and a feeling of the leg giving way or buckling.
Unsure if your pain is related to the SI Joint? Take this short 7-step quiz.
To appropriately diagnose a dysfunctional sacroiliac (SI) joint and prescribe the right treatment, your doctor will need your health history, including symptoms, a physical exam including the SI joint provocative maneuvers, and imaging studies. Your provider will also need to rule out other sources of low back pain such as the hip or spine, so there is less chance of misdiagnosis.
