The sacroiliac joint is more likely to suffer from chronic ligament sprain as there are numerous ligaments that connect the pelvis together and tether it to the sacrum.
Pain is most often felt just over and immediately surrounding the joint on either side of the low back.
However, a SI condition can refer pain as depicted here.
Sacroiliac Pain Pattern
Sacroiliac pain is most often caused by an injury that involves twisting, bending and lifting at the same time or from falls and accidents.
Pain arising from the SI joint can also be the result of leg length inequality that causes the pelvis to shift or tilt and creates stress in the same manner as if hinges were misaligned on the door. If the door hinges are not in the proper plane then the door will jamb when you attempt to swing it open or shut. This is kind of what happens when the right or left sacroiliac joints are positioned abnormally due to pelvic tilt. There will be motion stress or support stress when attempting to twist, bend or turn .
Just like most cases of lower back pain, once again prevention is the best action.
With any lower back pain it is imperative that proper spinal balance and alignment be addressed and that goes for the sacroiliac joints as well.
Failure to do so may prevent full recovery or relief of your chronic lower back pain even if the sacroiliac joints are not the origin of your pain.
