Buttock Pain Treatment in Chennai — SI Joint Pain & Piriformis Syndrome Specialist

The sacroiliac joint sits at the base of your spine, where the sacrum meets the iliac bones of the pelvis. It bears the full weight of your upper body every time you stand, walk, or climb stairs.

When this joint becomes inflamed, hypermobile, or injured — it generates pain that is almost always felt in the buttock.

It mimics lower back pain. It mimics sciatica. It is frequently misdiagnosed as a disc problem and treated accordingly — with no improvement, because the disc is not the issue.

SI joint dysfunction is more common than most people realise. It accounts for up to 25% of chronic low back and buttock pain cases — yet it is rarely investigated as the primary cause.

A fall or direct impact to the pelvis

Pregnancy (the hormone relaxin loosens pelvic joints, causing instability)

One leg longer than the other (leg length discrepancy)

Prolonged sitting or driving — especially relevant for patients who commute long distances along the GST Road corridor

Previous lumbar spine surgery (can transfer abnormal load to the SI joint)

Inflammatory conditions like ankylosing spondylitis

Pain on one side of the lower back and buttock — rarely both sides simultaneously

Pain that is worse when standing up from a seated position

Difficulty climbing stairs or walking uphill

Pain that radiates into the thigh but rarely travels below the knee

A feeling of instability in the pelvis when bearing weight

For cases where SI joint pain has become chronic and has not responded adequately to injections, Radiofrequency Ablation offers longer-lasting relief.

This procedure uses precisely targeted radiofrequency energy to interrupt the pain signals transmitted by the nerves supplying the SI joint. The result is sustained pain relief — typically lasting 12–18 months or longer — allowing the patient to engage fully in rehabilitation and regain function.

Deep in the buttock, directly beneath the gluteal muscles, lies the piriformis — a small but powerful muscle responsible for hip rotation. In approximately 17% of people, the sciatic nerve passes directly through this muscle rather than beneath it.

When the piriformis becomes tight, inflamed, or goes into spasm — it compresses the sciatic nerve. The result is pain that feels remarkably similar to sciatica from a disc problem — but originates entirely in the muscle, not the spine.

This is piriformis syndrome. It is consistently under-diagnosed because most imaging focuses on the spine, not the hip.

Office workers and IT professionals who sit for long hours without movement breaks

Factory workers and drivers who maintain the same hip position for extended periods

Runners and cyclists (overuse of the hip rotators)

People who have recently changed their footwear or started exercising after a long period of inactivity

Patients who have already had a lumbar MRI — which showed nothing significant — but still have persistent buttock and leg pain

Deep, aching pain in the centre of the buttock

Pain that radiates down the back of the thigh

Pain that is significantly worse when sitting for more than 20–30 minutes

Tenderness when pressure is applied directly over the buttock

Pain when climbing stairs or walking up an incline

Relief when lying down but immediate return of pain when sitting or standing

The key distinguishing feature: Piriformis syndrome pain is typically aggravated by sitting and relieved by movement — the opposite pattern to many disc-related conditions.

Immediate relaxation of the muscle spasm causing nerve compression

Rapid reduction in pain radiating down the leg

Restoration of sitting comfort — often within 48–72 hours

A therapeutic window during which rehabilitation exercises can begin effectively

Procedure time: 20–30 minutes. No sedation required. You can return to light activity the same day.

Buttock pain cannot be treated effectively without knowing its exact source. Is it the SI joint? The piriformis? The sciatic nerve at spinal level? A combination of two?

Dr. RajaRajan Balasubramanian conducts a systematic diagnostic evaluation — combining clinical examination, provocation testing, and imaging review — before recommending any treatment. Patients are never subjected to a procedure that has not been validated by a confirmed diagnosis.

Buttock pain that has persisted for more than 3 weeks without improvement

Pain in the buttock that radiates into the thigh or down the leg

Significant discomfort when sitting for more than 20–30 minutes

Buttock pain that returned after physiotherapy showed only temporary relief

You have had a lumbar MRI that showed no significant disc pathology — but the pain continues

Pain that disrupts your sleep or prevents you from walking, driving, or working comfortably

The longer buttock pain is left unaddressed, the more the surrounding muscles compensate — creating secondary pain patterns that take longer to resolve.

Early diagnosis = fewer treatment sessions. Faster recovery. Better outcomes.

The two most common causes of persistent buttock pain that require specialist assessment are Sacroiliac (SI) joint dysfunction and Piriformis Syndrome. SI joint pain is felt primarily on one side of the lower buttock and worsens with prolonged standing or stair climbing. Piriformis syndrome creates a deep, aching pain in the centre of the buttock that is significantly worse with sitting. Both conditions are frequently misdiagnosed as lower back pain or sciatica — which is why accurate diagnosis before treatment is essential.

True sciatica originates from nerve compression at the lumbar spine — typically from a disc herniation or spinal stenosis — and radiates from the lower back through the buttock and down the entire leg, often past the knee to the foot. Piriformis syndrome, by contrast, causes pain in the buttock and may radiate into the thigh, but rarely travels below the knee. SI joint pain is generally localised to one side of the lower buttock and does not typically radiate far down the leg. A clinical evaluation by a pain specialist — including provocation testing — can distinguish these conditions accurately.

Yes — in the vast majority of cases. Both SI joint dysfunction and piriformis syndrome respond well to non-surgical interventional treatments such as PRP injections, trigger point injections, and Radiofrequency Ablation for chronic SI joint pain. Surgery is rarely required for these conditions when they are correctly diagnosed and treated with precision interventional techniques.

One precise diagnosis. One targeted treatment plan. A clear path to sitting, standing, and moving without that deep, persistent ache.
