where is si joint pain felt

SI joint pain is typically felt in the lower back and buttocks area, right where the sacroiliac joint is located. It’s the joint connecting the sacrum at the base of your spine to the hip bones on each side. This can definitely cause an ache or sharp pain in the lower back or around the buttocks. Sometimes, it can also radiate down into the thighs, making it a bit confusing and easy to mistake for other issues like sciatica. The pain might get worse if you stand up after sitting for a long time, or when putting weight unevenly on one leg or twisting movements. Given its location and the ways it affects mobility, it makes sense that those might be activities where you notice it most.

When dealing with suspected SI joint pain, a physical examination can often be quite helpful in identifying whether the joint is really the source of the pain. A healthcare professional might perform specific maneuvers, such as the FABER test or Gaenslen’s test in order to pinpoint the issue, as these are ways to put stress on the sacroiliac joint to see if they reproduce your pain. Imaging studies, like X-rays or MRIs, are generally not the most useful for SI joint pain specifically but can rule out other causes like fractures or disc issues if you’ve experienced trauma.

Your doctor recommending physical therapy is a good step because it focuses on stabilizing the pelvis through strengthening and flexibility exercises, which can significantly help improve symptoms and function. It’s key to be consistent with the exercises your PT provides and communicate openly about any persistent or worsening pain. For more direct pain relief, sometimes corticosteroid injections directly into the sacroiliac joint can offer temporary relief and help confirm the joint as the source of pain. Talk to your doctor if after some time, physical therapy on its own isn’t providing enough relief or if alternative interventions like joint injections should be considered. However, it’s crucial not to rely solely on self-management, especially if pain continues or worsens. Continued dialogue with healthcare professionals will guide next best steps in achieving pain relief and return to normal activities.
