Does your back or butt hurt when you stand up or climb stairs? That pain’s origin could be your sacroiliac joint. Sacroiliac joint pain is one of the causes of chronic lower back pain, and walking, standing, and sitting may worsen the pain.
What is Sacroiliac Joint Pain?
Sacroiliac joint pain is a sharp, stabbing pain originating from your hips, lower back, and pelvis. This pain can move down to the legs, mainly along the back of the thighs, and usually occurs on one side.
The sacroiliac joint is a highly specialized joint located above the tail bone in your lower back. It connects the spine to the pelvis.
The sacroiliac joint absorbs the impact when walking. It also supports the upper body.
It functions by;
- Acting as a shock absorber by decreasing stress on the spine and the pelvis
- Transferring the load from the upper body to the lower body when standing and walking.
Main Causes of Sacroiliac Joint Pain
The sacroiliac joint has free nerve endings that can cause pain due to the degeneration and stiffness of these joints.
Causes of sacroiliac joint pain can be;
