Pain in the pelvis or buttock?
The problem might be coming from your back.
Are you receiving treatment for piriformis syndrome, sacroiliac joint dysfunction, or gluteal tendonitis without lasting success? This is often because the true cause is lumbar. Discover how nerve compression perfectly mimics pelvic problems.
The "False" Pelvic Problem
Persisting in treating the gluteal muscles with massage balls or infiltrating the sacroiliac joint when the sciatic nerve is pinched at its root in the back is a very common diagnostic error.
Anatomy & Pathology
The impact of the lumbar nerves on the pelvis
The nerves that give sensation and strength to your pelvis and buttocks all originate in your lower back (L4 to S1).
Root L1-L2
Origin: T12-L2Flexor control
(Iliopsoas muscle, hip flexors)
Sensory Zone
The groin crease • The upper and front of the thigh
False psoas tendinitis
Compression in the upper lumbar spine radiates directly into the groin. It is often confused with femoroacetabular impingement, psoas tendinopathy, or a muscle tear. The pain typically occurs when raising the leg (e.g., to get into a car).
Root L4
Origin: L3-L4Hip extensors
(Iliotibial band, tensor fascia lata)
Sensory Zone
Hip side (Greater trochanter) • Lowering onto the thigh
The Trochanteric Trap
A herniated disc at L3-L4 radiates directly to the side of the hip and pelvis. It is almost always misdiagnosed as a stubborn trochanteric bursitis, especially if the pain wakes you up at night.
Root L5
Origin: L4-L5Pelvic stability
(Gluteus minimus and medius, abductors)
Sensory Zone
Lateral side of the buttock and hip
Weakness and Limping
Compression of the L5 muscle causes weakness in the gluteus medius. It is often mistakenly treated as gluteus medius tendinitis. If you start to limp or walk with a "hip sway," L5 is the prime suspect.
Root S1
Origin: L5-S1Propulsion and Extension
(Gluteus maximus)
Sensory Zone
Center of the buttock (depth) • Back of the thigh
The Piriformis Imposter
Intense pain, like a "dagger" in the middle of the buttock. This is one of the most classic symptoms of a L5-S1 disc herniation, constantly mistaken for muscle syndrome Pear-shaped.
Differential Diagnosis
Pelvis or Lower Back? (Or both?)
To avoid painful and unnecessary manipulation of the gluteal muscles, it is imperative to determine the exact origin through a clinical evaluation.
How do we make the diagnosis?
Gluteal ultrasound vs. lumbar MRI
An ultrasound of the pelvis may show inflammation of the bursa or gluteal tendons. But only one lumbar MRI will allow us to see if the sciatic nerve (L5 or S1) is compressed, which would be the real cause of these muscle weaknesses.
Neurological Provocation Tests
We combine pelvic tests (FABER test, sacroiliac joint palpation) with back tests (Lasègue test / straight leg raise). If bending your back forward triggers pain in your buttock, the origin is lumbar!
The "Double Crushing" & Weakness
In many cases, gluteal contracture or bursitis is very real, but it has been provoked and maintained due to a problematic back.
The cascade of destruction of the basin:
- 1. Silent lumbar herniation L4-L5 or L5-S1
- 2. Decreased nerve impulses to the stabilizing gluteal muscles
- ↓
- 3. Pelvic instability during walking, excessive compensation
- 4. Piriformis muscle contracture or friction on the trochanter = Chronic Pain
Why do glute stretches fail?
You can stretch a contracted piriformis muscle as much as you want. If it contracts to compensate for instability caused by a pinched nerve in your back, the tension will inevitably return.
Consequence: Treating the buttock alone is a band-aid solution. For a permanent cure, the pelvic muscles must be "reconnected" by releasing the lumbar nerve root through the Spinal decompression therapy.
The Solution: Spinal decompression therapy
To the TAGMED CLINIC, We target the true neurological source of your pelvic pain. If your symptoms stem from sciatic nerve pain, local treatments (SI injections, deep gluteal massages) will only offer temporary relief.
The lumbar neurovertebral decompression is an advanced, non-invasive technology. By creating a computerized and specific stretch of the lower back, it generates negative intradiscal pressure. This shrinks herniated discs, rehydrates the discs, and releases the nerves (L4, L5, S1) that control your entire pelvis.
Effective for treating lumbar causes of pelvic pain:
- S1 radiculopathy perfectly mimicking piriformis syndrome
- Referred pain mimicking a blockage of the sacroiliac joint
- Weakness of the gluteus medius (L5 involvement) causing a limp
- Foraminal stenosis or lumbar hernia (L4 to S1)
- Stabbing pain in the buttock radiating to the thigh
Do not treat the symptom.
Address the root cause.
