Facet Joint-Related Low Back Pain

Common Symptoms

• Low back pain, often worse with extending or twisting the spine
• Pain that may be localized to one side, sometimes referring into the buttock or upper thigh but not typically below the knee
• Morning stiffness that improves somewhat with movement
• Pain relieved (diagnostically) by a medial branch nerve block targeting the facet joint

Why It Happens

The facet joints, like other joints in the body, can develop degenerative changes (osteoarthritis) over time, or become irritated from repetitive spinal extension and rotation, leading to localized inflammation and pain.

Why It Can Become Persistent

Because the facet joints move with essentially every spinal motion, ongoing daily activity can keep reproducing irritation, and degenerative joint changes generally don't reverse on their own.

Who Commonly Gets It

Facet-joint-related back pain becomes more common with age as the joints develop degenerative changes, and is more common in people whose activities or occupations involve repetitive spinal extension or rotation.

How It Is Usually Diagnosed

A clinical pattern of pain worse with extension/rotation raises suspicion, but the more definitive diagnostic step is a medial branch block — a targeted injection that temporarily numbs the nerves supplying a specific facet joint — used to confirm that joint as the actual pain source before more targeted treatment.

Traditional Treatment Options

• Physical therapy: Core and spinal stabilization exercises are a well-established first-line treatment.
• NSAIDs: Used for pain and symptom control.
• Medial branch block or facet joint injection: Both diagnostic and sometimes therapeutic.
• Radiofrequency ablation: A longer-lasting procedure for confirmed facet-joint pain that responds well to diagnostic blocks.

Why Someone Might Start Looking for Another Option

For people whose back pain has been specifically confirmed as facet-joint-related, and who'd prefer to explore non-invasive options before or alongside procedures like radiofrequency ablation, shockwave therapy has emerging evidence.

Where Shockwave Therapy May Fit

A sham-controlled randomized trial of 128 patients with medial-branch-block-confirmed facet joint pain found high-energy focused shockwave therapy produced substantially greater pain and disability improvement than sham treatment at 12 months, with MRI showing resolution of bone marrow edema (a sign of joint inflammation) in over half of treated patients. This is a well-designed, reasonably large trial for this kind of research — but we could only access it through a review summary rather than the original published article directly, so we'd recommend your provider review the primary source with you if this is being considered.

How Shockwave Treatment Works for This Area

Acoustic pressure waves are applied over the affected facet joint(s), generally alongside a spinal stabilization exercise program. This approach is specifically for pain that's been reasonably localized to the facet joints, not low back pain in general.

What the Treatment Feels Like

Most patients describe a firm tapping or pressure sensation over the lower back; your provider will discuss what to expect.

What Happens During Your First Visit

Your visit begins with a provider evaluation focused on your history and a physical exam relevant to your complaint. If shockwave therapy is determined to be clinically appropriate, your first treatment can typically be provided the same visit. See our What to Expect page for the full walkthrough.

Who May Not Be Appropriate

• Anyone whose back pain hasn't been evaluated to determine likely origin (facet joint vs. disc vs. nerve vs. other causes)
• Numbness, tingling, or weakness radiating down the leg, or other red-flag symptoms, which need their own evaluation
• Active infection, open wounds, or certain bone/spine conditions at the treatment site
• Pregnancy, in the treatment area, unless specifically cleared by your provider

This list is not exhaustive. Your provider will screen for contraindications during your evaluation.
