Procedure

Facet Block and Rhizotomy

A two-step treatment for spine pain that combines targeted joint injections with radiofrequency ablation of the nerves carrying pain signals.

Overview

Facet joint injections deliver anesthetic and anti-inflammatory medication directly into the small joints of the spine to reduce pain and inflammation. The injection also serves as a diagnostic tool — confirming which joints are generating pain.

When the injection provides meaningful but temporary relief, a follow-up radiofrequency rhizotomy can extend that relief. Rhizotomy uses controlled heat energy to disrupt the medial branch nerves transmitting pain signals from the facet joints, often providing months of durable relief.

What to Expect

The initial facet injection is placed under image guidance directly into the affected joints. If the injection confirms facet-mediated pain with temporary relief, a follow-up radiofrequency rhizotomy targets the responsible nerves for longer-lasting results.

What Recovery After Facet Joint Radiofrequency Ablation Typically Involves

Facet joint radiofrequency ablation is an outpatient procedure, and most patients plan for a short, structured recovery rather than an extended one. Understanding the usual timeline helps you prepare the days around your appointment and know which sensations are expected.

In the first 24 to 72 hours, it is common to notice soreness at the treatment site, and some patients describe a temporary increase in their usual pain as the treated nerves settle. This period varies from person to person. Applying ice intermittently and resting from strenuous activity are the measures providers most often suggest during this window. Many patients return to light daily routines within a day or two, though the clinical team will give guidance specific to your situation.

Because radiofrequency ablation interrupts the nerves that carry pain signals from the facet joints, relief is typically gradual rather than immediate. Some people notice a change within the first week; for others the benefit develops over two to three weeks as post-procedure inflammation resolves. This staged pattern is expected and does not indicate that the procedure was unsuccessful.

Activity, Follow-Up, and What to Watch For During Facet Joint Radiofrequency Ablation Recovery

Providers usually advise avoiding heavy lifting, vigorous exercise, and prolonged strenuous positions for a few days, then reintroducing activity as comfort allows. Gentle movement and walking are generally encouraged early, since prolonged inactivity can stiffen the surrounding muscles. If you were referred for physical therapy, your care team will indicate when to resume those sessions.

A follow-up visit is typically scheduled several weeks after the procedure so the clinical team can assess how the treated area is responding and discuss next steps. Patients who respond well often experience meaningful relief that lasts several months to longer, after which the treated nerves may regenerate and the procedure can be considered again if appropriate.

Certain symptoms warrant prompt contact with your provider: fever, spreading redness or drainage at the injection site, new weakness or numbness in the legs, or pain that intensifies well beyond the initial soreness. These are uncommon, but reporting them early allows your care team to evaluate you appropriately.

Keeping a simple log of your pain levels and activity in the weeks after the procedure gives your provider useful information at the follow-up visit and helps guide any adjustments to your overall plan.
