Brief Introduction of SI Joint
SI joint dysfunction or pain tends to appear as a sharp, stabbing pain that radiates from the hips and pelvis up to the lower back and down to the thighs. Sometimes it may feel numb and tingly, or as if your legs are about to buckle.
The SI joints are responsible for 15 to 30 percent of chronic lower back pain that people experience.
About 80 percent of adults in the United States will experience lower back pain during their lives. Lower back pain is a leading cause of missed workdays and the most common cause of job-related disability.
