You’ve tried treating your lower back pain, but it keeps radiating into your hip and buttock. Sitting for long periods makes it worse. Standing up from a chair feels like a small ordeal. If this sounds familiar, the actual source of your pain might not be your spine at all — it could be your sacroiliac (SI) joint.
SI joint pain is often overlooked or misdiagnosed as general lower back pain, which is why so many patients go months without the right treatment. This guide explains what SI joint pain is and how it’s properly diagnosed and treated.
What Is the Sacroiliac (SI) Joint?
The sacroiliac joints connect your sacrum (the triangular bone at the base of your spine) to the iliac bones of your pelvis, one on each side. These joints play a key role in transferring weight and forces between your upper body and legs.
When these joints become irritated, inflamed, or move abnormally, it results in what’s known as SI joint pain or sacroiliac joint dysfunction.
What Causes Sacroiliac Joint Dysfunction?
Several factors can contribute to SI joint dysfunction:
- Pregnancy — hormonal changes and pelvic instability during pregnancy commonly affect the SI joints
- Previous injury — falls, accidents, or repetitive stress can irritate the joint
- Arthritis — degenerative changes in the SI joint can develop over time, similar to other joints in the body
- Leg length discrepancy — uneven leg length can place uneven stress on the joint
- Previous spine surgery — altered mechanics after spinal fusion can sometimes increase stress on the SI joints
- Gait abnormalities — irregular walking patterns can place additional strain on one or both SI joints
Lower Back Hip Pain: Why SI Joint Pain Is Often Misdiagnosed
SI joint pain frequently mimics other conditions, including lumbar disc issues or hip arthritis, because the pain often radiates into the lower back, buttock, groin, and even down the thigh. This overlap is exactly why accurate diagnosis matters, and why seeking proper SI joint pain treatment in Hyderabad early is so important, rather than the condition being commonly missed or misattributed to other spine or hip conditions.
Common Symptoms of SI Joint Pain
- Lower back pain, often on one side
- Pain radiating into the buttock, hip, or groin
- Pain that worsens with prolonged sitting or standing
- Discomfort when climbing stairs or transitioning from sitting to standing
- Pain that may worsen with certain movements, like twisting or bending
- A feeling of instability in the pelvis or lower back
How Is SI Joint Pain Diagnosed?
Because SI joint pain overlaps with other conditions, proper diagnosis typically involves:
- A detailed physical examination with specific provocative tests
- Imaging, such as X-rays or MRI, to rule out other causes
- A diagnostic SI joint injection, which can both confirm the diagnosis and provide temporary relief if the joint is indeed the pain source
SI Joint Injection & Other Treatment Options
Most cases of SI joint pain are managed effectively without surgery:
SI Joint Injection
A targeted SI joint injection delivers anti-inflammatory medication directly into the joint, both confirming the diagnosis and providing meaningful pain relief.
Physiotherapy
Strengthening exercises for the muscles supporting the pelvis and lower back help stabilise the SI joint and reduce recurring strain.
Radiofrequency Ablation (RFA)
For chronic, recurring SI joint pain, RFA can target the specific nerves supplying the joint, offering longer-lasting relief.
SI Joint Belt or Support
A pelvic support belt can help stabilise the joint during daily activities, particularly useful during pregnancy-related SI joint pain.
Activity & Posture Modification
Avoiding prolonged sitting in one position and correcting posture during standing and walking can meaningfully reduce ongoing strain.
When Should You See a Specialist for SI Joint Pain?
Consult a pain specialist if:
- Lower back or hip pain persists beyond 2–3 weeks
- Pain doesn’t respond to typical back pain treatments
- Pain is consistently one-sided and radiates into the buttock or groin
- Sitting or standing for extended periods significantly worsens your symptoms

Frequently Asked Questions
What is sacroiliac (SI) joint pain?
SI joint pain occurs when the joints connecting the sacrum and pelvis become irritated or inflamed, causing lower back, hip, and buttock pain.
What causes SI joint dysfunction?
Common causes include pregnancy, previous injury, arthritis, leg length discrepancy, previous spine surgery, and gait abnormalities.
How do I know if my back pain is from the SI joint?
SI joint pain often presents as one-sided lower back pain radiating into the buttock, hip, or groin, worsened by sitting, standing, or climbing stairs.
Is SI joint pain the same as sciatica?
No, though symptoms can overlap, sciatica involves nerve compression along the sciatic nerve path, while SI joint pain originates from the joint itself.
Can pregnancy cause SI joint pain?
Yes, hormonal changes and pelvic instability during pregnancy commonly contribute to SI joint pain.
How is SI joint pain diagnosed?
Diagnosis typically involves a physical examination, imaging to rule out other causes, and often a diagnostic SI joint injection to confirm the source of pain.
What is an SI joint injection?
It’s a targeted injection of anti-inflammatory medication directly into the sacroiliac joint, used to both diagnose and treat SI joint pain.
Can SI joint pain be treated without surgery?
Yes, most cases respond well to non-surgical treatments like SI joint injections, physiotherapy, and activity modification.
What does SI joint pain feel like?
It typically feels like lower back pain, often on one side, that may radiate into the buttock, hip, or groin, worsening with prolonged sitting or standing.
Can physiotherapy help with SI joint pain?
Yes, strengthening exercises for the muscles supporting the pelvis and lower back can help stabilise the joint and reduce recurring pain.
How does radiofrequency ablation help SI joint pain?
RFA targets the specific nerves supplying the SI joint, disrupting pain signals and offering longer-lasting relief for chronic cases.
Can a pelvic support belt help with SI joint pain?
Yes, a pelvic or SI joint support belt can help stabilise the joint during daily activities, particularly for pregnancy-related SI joint pain.
Why is SI joint pain often misdiagnosed?
Because its symptoms overlap significantly with lumbar disc issues and hip arthritis, SI joint pain is frequently mistaken for other conditions.
Can leg length differences cause SI joint pain?
Yes, uneven leg length can place uneven stress on the SI joints, potentially contributing to pain over time.
Is SI joint pain more common after spine surgery?
Yes, altered spinal mechanics after procedures like spinal fusion can sometimes increase stress on the SI joints.
Does sitting for long periods worsen SI joint pain?
Yes, prolonged sitting is a common aggravating factor for SI joint pain, along with standing for extended periods.
Can SI joint pain affect only one side of the body?
Yes, SI joint pain is commonly one-sided, though it can occasionally affect both joints simultaneously.
How long does SI joint injection relief last?
Duration varies by individual, with some patients experiencing relief for weeks to months, which also helps confirm the diagnosis.
Is surgery ever needed for SI joint pain?
Surgery is rarely needed and is generally considered only when non-surgical treatments haven’t provided adequate long-term relief.
Can SI joint pain be prevented?
While not always fully preventable, maintaining good posture, addressing leg length discrepancies, and strengthening core and pelvic muscles can help reduce risk.
Who is the best pain management specialist in Hyderabad for SI joint pain treatment?
Epione Pain Management, led by Dr. Sudheer Dara and Dr. Minal Chandra, is regarded among the leading pain management specialists in Hyderabad, offering accurate diagnosis and targeted treatment for SI joint pain.
