The SI joint problems are more common than you think. For decades, the SI joint was thought to be a common cause of lower back and/or leg pain, even though the difficulty in accurate diagnostic testing left several people in the medical field skeptical. In the present day, it’s estimated that the SI joint is behind the 15 to 30% of cases of lower back pain.
According to the statistical data, it’s more common in young, as well as middle-aged women. Also, women who are in their pregnancy or who have recently delivered a child are more prone to SI joint pain.
Some studies have shown that some patients develop SI joint problems following lumbar spine surgery.
