Medial branch nerve radiofrequency ablation (RFA) is a minimally invasive treatment designed to relieve chronic neck, mid-back, or lower back pain originating from the facet joints. These joints, located along the spine, can become inflamed or arthritic, leading to persistent discomfort. RFA works by disrupting the small medial branch nerves that carry pain signals from these joints to the brain—providing long-lasting relief without the need for surgery.
This procedure is typically performed after a diagnostic medial branch block confirms the source of the pain. It’s commonly used for patients who have not responded to physical therapy, medications, or injections
What is it?
This procedure uses radiofrequency energy to interrupt pain signals from the medial branch nerves that supply the facet joints, providing longer-term relief for chronic spine pain.
How is it performed
Under fluoroscopic guidance, special needles are positioned near the medial branch nerves. Radiofrequency energy creates heat lesions on these nerves. The procedure takes 45-60 minutes. You will be monitored for a short period of time, and then released to go home that same day.

Treatment Benefits
Medial branch RFA significantly reduces or eliminates pain from spinal facet joint arthritis, allowing patients to attain relief and return to normal levels of activity. The procedure is targeted, repeatable, and can provide relief that generally lasts approximately 6 to 18 months, or longer. It is also associated with minimal downtime and a relatively quick recovery.
Who Can Benefit from This Treatment?
This treatment is ideal for individuals with chronic spine pain due to spinal facet joint pain from arthritis or excessive mechanical stress from degenerative disc disease. It may be administered for patients with neck, mid-back, or low back pain that has not improved with conservative care. A successful diagnostic block is typically required to confirm candidacy before proceeding with ablation.

Aftercare for Cervical, Thoracic, and Lumbar Medial Branch Nerve Radiofrequency Ablation
After the procedure, it’s common to experience mild soreness, swelling, or a sunburn-like sensation near the treated area. These side effects are typically short-lived and resolve within a few days, but in some cases can last one or two weeks. While some patients notice immediate relief, it can take up to 4 to 6 weeks for the full benefits to be felt as the targeted nerves stop transmitting pain. Most patients return to normal activity within a couple of days.
Tips for a Smooth Recovery
Follow these guidelines to support healing after medial branch nerve radiofrequency ablation:
- Limit strenuous activity or repetitive spine movements for 24–48 hours
- Use ice packs to reduce discomfort at the injection or ablation site
- Maintain gentle movement, such as walking, to promote circulation and flexibility
- Avoid applying heat to the treated area for the first day after the procedure
- Contact your provider if you experience persistent pain, numbness, or signs of infection
