Sacroiliac joint pain (SIJ) typically presents as a sharp, stabbing, or dull ache in the lower back, specifically in the region where the spine meets the pelvis. The pain is often felt on one side of the lower back or buttocks but can occasionally affect both sides. It may radiate down to the groin, thigh, or even the leg, mimicking sciatica.
Common sensations associated with SI joint pain include:
- Localized pain: A deep, aching discomfort in the buttocks or lower back.
- Sharp pain: Sudden, intense pain, especially when moving or changing positions, such as getting up from a chair or rolling over in bed.
- Stiffness: Reduced range of motion in the lower back, making bending or twisting movements uncomfortable.
- Pain when pressure is applied: Tenderness in the area of the SI joint, especially when pressing directly on the joint or the Piriformis muscle.
- Pain with prolonged sitting or standing
- Pain that worsens after sitting or standing for extended periods.
- Pain that improves with movement: In some cases, light movement or walking can help relieve discomfort. The intensity and nature of SI joint pain can vary widely from person to person and may fluctuate throughout the day depending on activities and posture.
A Physiotherapy assessment is useful to determine the cause and there are many manual therapy treatment techniques for the SIJ as well as a home program usually aimed at the piriformis and glut medius muscles.
