Since the SI joint is in the lower back, sitting can be painful because it places pressure on the hips and lower spine. The best way to sit with SI joint pain is in a way that relieves that pressure as much as possible. Some suggestions are:
- Sit in a relaxed position with a cushion or a rolled towel placed behind the back
- Sit upright with your chest pressed upward and the shoulder blades relaxed
- Sit with your feet crossed while placed underneath your legs and pulled back towards the hips (called a tailor’s position)
- Sit with the knees apart and turned out slightly
You will have to try the various sitting positions to determine which ones most ease the pain.
