Epidural steroid injections may reduce inflammation and temporarily calm nerve irritation, but they do not repair annular tears or regenerate damaged disc tissue — so pain often returns once the medication wears off. For many patients with chronic disc-related back pain, biologic disc repair may offer a more durable path forward; candidacy is evaluated individually and outcomes vary.

The Cycle of Temporary Relief: Understanding Injections

Epidural steroid injections (ESIs) and nerve blocks are among the most commonly recommended treatments for back pain when inflammation or nerve compression is suspected. They deliver powerful anti-inflammatory medication directly to the area around the spinal nerves, or block pain signals from specific nerves entirely. For some patients — particularly those with acute, recent-onset pain — injections can be effective, providing a window for physical therapy and natural healing to take hold.

For many individuals living with chronic back pain, however, the pattern is different. Relief may last weeks or a few months, but the pain frequently returns. Understanding why requires a closer look at what injections actually do — and what they do not.

Masking Symptoms vs. Addressing the Cause

The central limitation of ESIs for chronic pain lies in their mechanism: they reduce inflammation and calm irritated nerves, but they do not repair damaged tissue, regenerate degenerated discs, or close annular tears. When the structural problem causing inflammation persists, discomfort often returns once the steroid’s effect fades.

Think of it like mopping water off a floor without fixing the leaking pipe above it. The puddle clears temporarily, but the root problem remains. If a damaged disc or annular tear is the pain source, reducing local inflammation around it does not resolve the underlying structural compromise.

Clinical literature — including a systematic review published by the American Academy of Family Physicians — has noted that ESIs show limited effectiveness for chronic low back pain, underscoring their role as a short-term management tool rather than a long-term solution for persistent structural disc pain.

Expert Take

Our clinical team frequently evaluates patients who have received three or more rounds of injections without sustained benefit. In many of these cases, imaging reveals annular tears or significant disc degeneration — structural problems that anti-inflammatory medication cannot resolve. Early identification of the root cause often opens the door to more targeted, potentially longer-lasting treatment options.

Unmasking the Root Cause: Disc Damage and Annular Tears

Breaking the cycle of temporary relief begins with identifying the true source of chronic back pain. While multiple factors can contribute, two of the most common — and frequently overlooked — are annular tears and degenerative disc disease.

The Role of Intervertebral Discs

Your spine is made up of vertebrae cushioned by intervertebral discs. These discs act as shock absorbers, enabling flexibility and movement. Each disc has a tough outer layer — the annulus fibrosus — and a gel-like inner core called the nucleus pulposus. When the annulus is compromised, it can trigger a cascade of pain-generating events.

Annular Tears: A Hidden Source of Chronic Pain

An annular tear is a fissure in the disc’s outer fibrous ring. Tears can develop from injury, repetitive mechanical stress, or the natural aging process. When one forms, inflammatory chemicals from the nucleus pulposus may leak outward and irritate nearby spinal nerves — producing significant pain even without obvious nerve compression on imaging. The tear itself also contains nerve endings and may be a direct, independent pain source.

Beyond the immediate discomfort, annular tears compromise disc structural integrity, contributing to instability and further degeneration over time. They can also be a precursor to herniated or bulging discs. Because anti-inflammatory injections do not close or heal these tears, the pain generator persists. For a deeper look at how tears drive chronic symptoms, see our guide on annular tears and chronic back pain.

Degenerative Disc Disease (DDD)

Degenerative disc disease reflects the gradual age-related loss of disc hydration, elasticity, and height. As discs degenerate, they become more susceptible to tears and may allow for nerve compression as disc height decreases. When DDD coexists with annular tears, the combination creates a chronic pain environment that symptom-masking treatments are unlikely to resolve on their own.

Beyond Temporary Fixes: The Case for Biologic Disc Repair

Because chronic back pain so often stems from structural disc damage, treatments that help repair the disc may offer more durable relief than those that only manage symptoms. This is where intra-annular fibrin injection — a form of biologic disc repair — becomes relevant.

What Is Intra-Annular Fibrin Injection?

Intra-annular fibrin injection is a minimally invasive, regenerative procedure designed to address annular tears and support stabilization of degenerative discs. Rather than masking pain, the fibrin procedure aims to seal the tear and encourage the body’s own healing processes within the disc.

The procedure involves injecting a fibrin biologic — a natural protein central to wound healing and clotting — directly into the damaged annulus under image guidance. Once in place, the fibrin acts as a biological scaffold, working to:

• Seal the annular tear, helping contain inflammatory chemicals and reducing nerve irritation
• Stabilize the disc, potentially reducing pain associated with disc instability
• Provide a structural matrix that may support the body’s natural tissue repair response

The procedure is typically performed on an outpatient basis, avoiding the risks and extended recovery associated with open spine surgery. Learn more about how the fibrin procedure compares to surgical approaches in our overview of biologic disc repair vs. traditional spine surgery.

Why Biologic Disc Repair May Offer More Durable Relief

The distinction between symptom management and structural repair matters for patients seeking lasting improvement:

• Targets the root cause: Fibrin disc treatment directly addresses the annular tear — often the primary pain generator — rather than simply reducing surrounding inflammation.
• Minimally invasive: Image-guided, outpatient delivery reduces procedural risk and recovery time compared with major spinal operations.
• Supports natural healing: The fibrin scaffold encourages the body’s own regenerative processes, rather than replacing or bypassing them.
• Evaluated individually: Candidacy is determined through thorough diagnostic assessment, including MRI review; outcomes vary by patient and condition severity.

Published clinical data on fibrin disc treatment show meaningful reductions in pain scores over follow-up periods extending beyond two years in many patients, and the approach has shown promise even in cases of prior failed back surgery — though individual results vary.

Comparing Your Non-Surgical Options

Intra-annular fibrin injection is not the only non-surgical option, and it is important to understand how different approaches differ in their mechanisms and goals:

• Physical therapy: Essential for rehabilitation and functional strengthening, but PT alone cannot mechanically close or heal a structural annular tear.
• Chiropractic care: May provide symptomatic relief by improving spinal mechanics, but does not directly repair disc damage.
• PRP injections: Platelet-rich plasma has shown promise for some musculoskeletal conditions and early disc regeneration research, but differs mechanistically from fibrin treatment, which is specifically designed to seal annular defects.
• Spinal decompression therapy: Some patients report temporary symptom reduction, but long-term sustained improvement rates in available studies are modest and the approach does not fundamentally address disc structural integrity.
• Epidural steroid injections: Useful for acute inflammation management; less effective for chronic structural disc pain, as discussed above.

Who May Be a Candidate for Biologic Disc Repair?

Patients are evaluated individually. A consultation and thorough diagnostic workup — typically including MRI — are required to determine whether fibrin disc treatment may be appropriate. Common characteristics that often prompt evaluation include:

• Chronic low back pain or sciatica persisting for several months or longer
• MRI findings consistent with degenerative disc disease or annular tears
• Prior conservative treatments — physical therapy, chiropractic care, or multiple rounds of injections — without lasting relief
• A preference for minimally invasive options before considering spinal surgery
• Prior back surgery with continued or recurrent pain (failed back surgery syndrome)

Expert Take

When a patient has had two or more rounds of epidural injections without sustained improvement, our clinical team considers that a meaningful signal to investigate structural disc pathology more carefully. In many such cases, annular tears that were not initially identified turn out to be the primary driver of ongoing pain. Addressing that structural problem — rather than repeating anti-inflammatory treatments — is often the more logical next step for appropriately selected patients.

A Patient-Centered Approach to Spine Care

At Valor Spine, our approach centers on identifying the precise source of each patient’s pain before recommending any treatment. We recognize that the same symptom — chronic low back pain — can arise from very different structural problems, and that treatment plans should reflect those differences. Our focus on non-surgical spine solutions means we actively explore biologic disc repair and other regenerative options for patients who have not found lasting relief through conventional approaches.

Veterans represent a population we are particularly committed to serving. Low back pain is among the most common service-connected conditions, and many veterans have been through multiple rounds of injections or have been told surgery is their only remaining option. We evaluate each veteran’s case individually and explore whether non-surgical pathways — including fibrin disc treatment — may be appropriate. Learn more about our approach in 5 non-surgical back pain relief options for veterans.

If you are tired of the cycle of temporary relief and want to explore a treatment that targets the structural source of your back pain, we invite you to schedule a consultation with our clinical team to discuss whether biologic disc repair may be appropriate for your individual situation.
