Deep gluteal syndrome: buttock pain and sciatica without a spinal cause
Deep buttock pain and leg symptoms but a normal spine MRI?
The myBackPain assessment identifies the deep gluteal syndrome pattern — buttock-dominant pain without true spinal nerve root features — and distinguishes it from disc-related sciatica. Results in minutes.
What is deep gluteal syndrome?
Deep gluteal syndrome describes pain and nerve irritation arising from the deep gluteal space — the area beneath the gluteal muscles where the sciatic nerve passes through or below the piriformis muscle. When the piriformis muscle becomes tight, inflamed, or develops trigger points, it can compress or irritate the sciatic nerve, producing symptoms that closely mimic disc-related sciatica.
It is one of the most common causes of “sciatica” that is not actually coming from the spine, and it requires different management. Treating the spine when the cause is in the deep gluteal space produces poor results.
MRI of the lumbar spine is often normal or shows only minor changes that are not consistent with the clinical picture. The diagnosis is a clinical one, made by identifying characteristic buttock tenderness, reproduction of symptoms with provocation tests (the FAIR test — hip flexion, adduction, internal rotation), and the absence of true dermatomal neurological findings on examination.
What does it feel like?
- Deep, aching buttock pain — often unilateral
- Pain radiating down the posterior thigh — usually not below the knee
- Worse with prolonged sitting, particularly on hard surfaces
- Worse with hip internal rotation and adduction — crossing legs, sitting with feet turned in
- Tenderness on deep palpation of the piriformis muscle in the buttock
- Often no neurological changes on examination — no reflex change, no dermatomal sensory loss
What helps?
Soft tissue therapy
Deep tissue massage and trigger point release to the piriformis and surrounding deep gluteal muscles is the primary treatment. Often produces immediate and significant relief. Best delivered by an osteopath, physiotherapist, or sports therapist.
Stretching
Specific piriformis stretches — the figure-4 stretch in sitting or lying positions — are highly effective. Should be performed daily as part of ongoing self-management. Maintain throughout recovery.
Hip strengthening
Gluteal strengthening addresses the underlying hip dysfunction that typically contributes to piriformis overload. Weak glutes cause the piriformis to work harder as a compensator, maintaining the cycle of irritation.
Activity modification
Avoiding prolonged sitting, adjusting driving position, using a coccyx cutout cushion on hard surfaces, and avoiding positions that internally rotate and adduct the hip.
