Sacroiliac joint pain is a common but often misunderstood source of lower back and pelvic discomfort. At Pain Management Centers of America (PMCOA), our board-certified interventional pain specialists help patients identify the cause of sacroiliac (SI) joint pain and tailor a personalized treatment plan that reduces pain, improves function, and enhances quality of life.
What Is the Sacroiliac Joint?
The sacroiliac joints are two strong, weight-bearing joints where the sacrum — the triangular bone at the base of the spine — meets the pelvis (ilium) on each side. These joints play a key role in transferring weight and stress between your upper body and legs.
Sacroiliac joint pain occurs when these joints become irritated, inflamed, unstable or dysfunctional. This can happen from a variety of causes, and the pain can be confusing because it often mimics other back, hip, or pelvic conditions.
Common Causes of Sacroiliac Joint Pain
Sacroiliac joint pain may stem from a number of factors, including:
- Inflammation — Conditions like sacroiliitis or arthritis can inflame the joint.
- Trauma or injury — Falls, motor vehicle accidents, or sudden twists can strain the SI joint.
- Post-surgical changes — Previous lumbar spine surgery may alter mechanics and load the SI joints.
- Pregnancy — Hormonal and mechanical changes can loosen ligaments and stress the joint.
- Muscle imbalance or abnormal gait — Uneven movement can place extra pressure on one SI joint.
Sometimes the exact cause isn’t clear, which is why proper evaluation and diagnosis are crucial.
Signs & Symptoms to Watch For
SI joint pain can vary from a dull ache to sharp, stabbing sensations and is often felt:
- In the lower back or buttocks
- In the hips, groin, or legs
- With prolonged sitting, standing, stair climbing, or walking
- When moving from sitting to standing
Because these symptoms can overlap with other conditions, a comprehensive assessment by a pain specialist can help pinpoint the true source of pain.
How PMCOA Approaches Diagnosis
At PMCOA, we start with a detailed history and physical exam to assess your pain pattern and how it affects movement. Imaging and diagnostic injections can assist in confirming whether the SI joint is the source of your symptoms.
Treatment Options at PMCOA
PMCOA offers a full range of evidence-based interventional pain management services for sacroiliac joint pain, including:
Conservative Care
- Physical therapy
- Anti-inflammatory medications
- Activity modification and movement strategies
These foundational approaches focus on reducing mechanical stress and strengthening supporting muscles.
Interventional Procedures
When conservative care isn’t enough, PMCOA provides minimally invasive treatment such as:
- Sacroiliac joint injections to reduce inflammation and confirm the pain source.
These procedure is performed under imaging guidance by our experienced physicians to ensure both safety and effectiveness.
