SI Joint Pain
Evaluating pain where the base of the spine meets the pelvis before deciding on treatment.
Request My ConsultationUnderstanding si joint pain
The sacroiliac, or SI, joints connect the sacrum at the base of the spine to the pelvis. Pain from this area can overlap with symptoms from the lower back or hips. Sacroiliitis specifically means inflammation of an SI joint.
Common symptoms
- Pain around the lower back or buttock.
- Discomfort with standing, walking, or changing position.
- Symptoms that can resemble other lower-back or hip problems.
What can cause it?
SI joint symptoms can involve mechanical stress or inflammation. Inflammatory arthritis, including ankylosing spondylitis, is one possible explanation. The cause matters because treatment of an inflammatory condition differs from treatment of an isolated mechanical joint problem.
How it is evaluated
Evaluation examines the back, hips, and pelvis. Specific examination maneuvers help assess whether the SI joint reproduces the pain. Imaging may be useful, and a targeted numbing injection can sometimes help clarify the source.
Treatment considerations
These are general educational options. A consultation helps determine what is appropriate for your diagnosis and health.
