Sacroiliac Joint Pain

Sacroiliac (SI) joint pain refers to discomfort or pain that originates from the sacroiliac joints, which are located where the sacrum (the triangular bone at the base of the spine) meets the iliac bones of the pelvis. These joints help support the weight of the upper body and provide stability during movement. SI joint pain can result from inflammation, injury, or dysfunction in these joints, leading to lower back and pelvic pain.
 
SI joint pain may develop due to a variety of factors, including trauma, arthritis, pregnancy, or uneven leg length, and can mimic other conditions like sciatica or lumbar disc issues. It often affects one side of the lower back and can radiate into the buttocks, hips, or legs.

Common Symptoms

  • Dull, aching pain in the lower back or buttocks
  • Pain that radiates to the hips, groin, or thighs
  • Stiffness or a feeling of reduced mobility in the lower back, especially after sitting for long periods or upon waking
  • Pain that worsens with activities like standing, walking, climbing stairs, or lifting objects
  • Pain that improves when lying down or shifting weight to the other side
  • Tenderness or soreness over the SI joint
  • Difficulty with movements that involve twisting or bending the lower back
  • A sensation of instability in the pelvis or lower back
  • Pain that radiates down one leg, similar to sciatica
  • Worsening pain when transitioning from sitting to standing or standing on one leg
