Sacroiliac (SI) Joint Dysfunction

Sacroiliac or SI joint dysfunction generally refers to pain in the sacroiliac joint region. The sacroiliac joint is a large joint located in the lower back. 

The pain is most often the result of abnormal motion in the sacroiliac joint, either too much or too little. Most often, it results in inflammation of the sacroiliac joint.

Common symptoms include:

  • Lower back pain, buttocks pain, sciatic leg pain, groin pain, hip pain
  • Urinary frequency
  • Numbness, prickling, or tingling

Pain can range from dull aching to sharp and stabbing and increases with physical activity. Symptoms also worsen with prolonged or sustained positions.
