Located either side of the spine, Sacroiliac joint pain occurs as a result of the torsional or twisting forces that are applied to the pelvic girdle when the legs are in motion.
Although it is essential that these joints allow movement (if they didn't, the pelvis would be subject to fractures), Sacroiliac joint pain can if the joints get stuck or twisted to one side or the other - this is called a twisted pelvis.
This can irritate the Iliolumbar ligament and cause inflammation and pain, which will be felt around the bony lumps on either side of your lower back.
Causes can vary - this is very common after pregnancy, when the pelvic joints have relaxed in preparation for childbirth. Other causes are usually mechanical, although there may be other medical conditions present such as Ankylosing Spondylitis.
- Pain on either side of your lower back - this pain can radiate out into your butt, and even to the front, into the groin, or into the lower limbs
- Difficulty turning over in bed
- Difficulty putting on shoes and socks
- Pain and difficulty getting your legs in and out of the car
- Low back stiffness
Treatment includes rest, anti-inflammatory medication, manipulation, sports massage, and ice treatments to reduce inflammation.
