SI Joint Pain: Causes, Symptoms And Treatment

SI joint pain can cause a wide range of uncomfortable symptoms. Numbness, pain, and tingling may be felt in the lower back, buttocks, hips, or radiate down the leg. Because these symptoms are similar to other common conditions, SI joint pain is often misdiagnosed. At Airrosti we take the time to fully evaluate your pain to pinpoint the root of the injury to treat it at the source. Unlike traditional methods of treatment, Airrosti’s method eliminates pain in an average of three visits.


The sacroiliac joint, or SI joint, is located in the pelvis, linking the iliac bone (pelvis) to the sacrum (lowest part of the spine above the tailbone). This joint transfers weight and forces between your upper body and legs. It is an essential component for shock absorption that prevents impact forces felt during walking from reaching the spine.

The SI joint is stabilized by a network of ligaments and muscles, which also limit motion. The normal sacroiliac joint has a small range of motion of approximately 2-4 mm of movement in any direction. Like any other joint in the body, the sacroiliac (SI) joint can degenerate and its support ligaments can become loose or injured. When this happens, people can feel pain in their buttock and sometimes even well above their buttock. This is especially true with lifting, running, walking, or even sleeping on the involved side.

Clinical literature shows that up to 25 percent of low back pain can be attributed to the SI joint. Chronic SI joint pain can make it difficult to perform common daily tasks and affect every aspect of a patient’s life. Common complaints from patients suffering from SI joint pain include lower back pain; sensation of lower extremity pain, numbness, tingling, or weakness; pelvis/buttock pain; hip/groin pain; feeling of leg instability; disturbed sleep patterns; inability to sit for long periods of time; pain going from sitting to standing.

This source of pain can be caused by either too much movement or too little movement. When caused by too much movement, the pain is typically felt in the lower back and/or hip and may radiate into the groin area. When caused by too little movement, the pain is typically felt on one side of the low back or buttocks, and can radiate down the leg. The pain usually remains above the knee, but at times pain can extend to the ankle or foot.


Accurately diagnosing sacroiliac joint dysfunction can be difficult because the symptoms mimic other common conditions. As a result, many SI Joint conditions are misdiagnosed and mistreated. This leads to expensive diagnostics and imaging. Often these costly procedures do not change the course of treatment. Treatment usually consists of rest and icing, pain medication, physical therapy, and joint injections.

Airrosti is different. Our providers are expertly trained to evaluate the specific cause of your symptoms. A more detailed evaluation leads to an accurate diagnosis, followed by highly specific manual therapy and active rehab to correct the underlying cause. In nearly all cases, this allows for rapid recovery, complete resolution, and lasting results.
