The sacroiliac (SI) joints are the joints in the lower back, where the sacrum (the flat triangular bone of the spine) and ilium (hip bone) connect.
- The sacrum is a triangle-shaped bone toward the bottom of the spine, slightly above the coccyx (the tailbone).
- The ilium is the uppermost part of the pelvis, and it is one of the three bones that make up the hip.
They work as shock absorbers, reducing the pressure placed on the spine by movement.

Causes of sacroiliac joint pain
Sometimes, if movement in the pelvis is not equal on both sides, SI pain can occur.
Regular activities, such as sitting, standing, sleeping, walking, or climbing stairs, may aggravate symptoms. Sitting or sleeping on the affected side often causes more pain in the SI joint.
Symptoms of sacroiliac joint pain
Sacroiliac (SI) joint discomfort is often described as a sharp, stabbing ache that travels from your hips and pelvis to the lower back and legs. It could sometimes feel numb or like pins and needles sort of pain.
Weakness in the sacroiliac joint can cause lower back, buttocks, or leg pain. Leg pain produced by sacroiliac joint dysfunction can be difficult to distinguish from lumbar disc herniation or hip problems. The two can feel quite similar. Hence, an accurate diagnosis is necessary.
