What Causes SI Joint Pain?

There are two SI joints in the human body – a left SI joint and a right SI joint. Both can be found in the posterior pelvic region. They are called sacroiliac joints because they are found specifically in the space between the sacrum and the ilium bones.

SI Joint activities to avoid

The role of the SI joints is to ensure the pelvis maintains a neutral alignment. But these joints tend to be more stressed during pregnancy. The stress is due to two factors. The first is the presence of relaxin – a hormone that softens the ligaments and makes the pelvis stiff. Relaxin helps the body to accommodate the developing baby and ensure mobility during childbirth conveniently. However, the downside is that it reduces pelvic stability.

The stability even decreases further with the growth of the belly, which is the second factor. The pelvis is pushed forward such that the SI joint struggles to align the pelvis naturally.

Both factors force the SI joint to become hypermobile, leading to pain in the body. Relaxin continues to perform the same functions even after childbirth. Therefore, it is possible to experience SI joint pains after giving birth.

How to Sit with SI Joint Pain?

People with sacroiliac joint issues tend to worry about the most comfortable way to sit or the sitting position that allows them to self-mobilize and be comfortable. The simple answer to this is to get a proper chair and adopt the right sitting posture.

The ideal chair should keep your hips and knees at the same level or the former slightly higher. This posture ensures seamless hip shifting. Any other chair configuration – where the knees are too high for the hips, or vice-versa, will be counterproductive.

For another, the best chair for the SI joint should also come with the ideal lumbar support for both sitting and moving around in the chair.
