Some back pain radiates. Discogenic pain usually does not. It sits deep and central in the low back, worsens when you sit, and eases when you lie flat — and it is one of the most commonly misdiagnosed causes of chronic back pain. At Remix Medical in Houston, our pain management physicians use provocative discography to determine whether a specific disc is the true source of your pain.
What is Discogenic Back Pain?
Discogenic back pain originates inside the intervertebral disc itself, not from a nerve being compressed by it. The outer wall of a healthy disc, the annulus fibrosus, contains nerve fibers only at its periphery. When that wall tears or degenerates, those nerve endings grow inward toward the disc's core and become sensitized.
The result is axial pain — pain in the back rather than down the leg. It is a different problem from sciatica, and it responds to different treatment.
Common Causes of Discogenic Back Pain
1. Annular Tears
A tear in the outer wall of the disc allows inflammatory chemicals from the nucleus to reach nerve endings that were never meant to encounter them.
2. Internal Disc Disruption
The disc's internal architecture breaks down without any visible bulge or herniation. The disc looks nearly normal on imaging and hurts considerably.
3. Degenerative Disc Disease
Progressive loss of disc height and hydration mechanically overloads the annulus, making tears more likely.
4. Repetitive Loading and Trauma
Heavy lifting, prolonged seated work, vibration exposure, and motor vehicle collisions all concentrate stress at the disc.
Symptoms of Discogenic Back Pain
- Deep, aching, central low back pain
- Pain that worsens with sitting, forward bending, coughing, or sneezing
- Relief when lying down or standing upright
- Pain that does not follow a clear nerve distribution down the leg
- Occasional referred pain into the buttock or posterior thigh, rarely below the knee
- Morning stiffness that eases with gentle movement
How Remix Medical Can Help
The diagnostic challenge is real: MRI frequently shows degenerative changes in people with no pain at all, and can look unimpressive in people whose disc is clearly the culprit. Imaging tells us what a disc looks like. It does not tell us whether that disc hurts.
Provocative discography closes that gap. Under fluoroscopic guidance, contrast is introduced into a disc and the patient reports whether the resulting sensation reproduces their familiar pain. Adjacent discs serve as controls. When a single level reproduces the pain and its neighbors do not, we have identified the pain generator.
From there, our treatment options include:
- Epidural steroid injections to reduce inflammation at the affected level
- Medication management for inflammatory and neuropathic components
- Physical therapy referral emphasizing core stabilization and load management
- Ergonomic and activity counseling, particularly for seated occupations
- Referral for surgical consultation when conservative care is exhausted
| Approach | What it involves |
|---|---|
| Physical therapy + activity change | Core stabilization and movement retraining — first-line for most spine pain |
| Medications | Anti-inflammatories, nerve-pain agents, and short-term muscle relaxants |
| Image-guided injections | Epidural steroid or nerve blocks placed precisely to calm the irritated nerve |
| When to consider surgery | Reserved for nerve compression with weakness, or pain that fails everything else |
