The sacroiliac joints (SIJ) are formed between the sacrum, a triangular-shaped bone in the lower portion of the spine, and the right and left ilium of the pelvis. The main role of the SIJ is to allow forces to be transmitted effectively through the body, absorbing impact from the legs to the spine during activities such as walking, running and jumping.
The joint, also called the SI joint, restricts the movement of the lower body and any awkward or abnormal movement can cause the joint to dysfunction. Sacroiliac joint pain is typically discomfort that is centrally located in the lower back and hip area. Severe cases of Sacroiliac back pain can spread into the legs and groin. Aging can also cause sacroiliac joint dysfunction as the muscles around the joint start to stiffen.
1. Pain in lower back and hips
2. The pain usually appears on the left-hand side of the body.
3. Generally aggravated by sitting, standing, or bending at the waist

Pregnancy may be a factor in the development of joint problems. During pregnancy, hormones are released that lets ligaments relax. If a person has one leg which is shorter that the other, the abnormal alignment may cause joint pain.
