Radiofrequency Ablation (RFA): Turning Down the Volume on Chronic Pain

Background / Overview

Chronic pain isn’t always loud—it can be a dull ache that hums beneath your daily life, making everything a little harder: sitting at your desk, picking up your child, sleeping through the night. If that pain keeps coming from the same spot in your back or neck, and if it’s been traced to the facet joints or medial branch nerves, you might be a candidate for radiofrequency ablation (RFA).

RFA is a minimally invasive procedure that uses heat to “turn off” the nerves sending pain signals from your spine to your brain. Think of it like lowering the volume on a blaring speaker—only this speaker is in your body, and it’s been playing nonstop.

It’s not a cure, but for many people, RFA provides significant, long-lasting relief—sometimes for 6 to 12 months or more.

Symptoms and Causes

RFA is typically used to treat chronic neck, mid-back, or lower back pain—especially when that pain comes from the facet joints, which are small joints located between each vertebra. It may also help with sacroiliac joint pain and even certain types of knee or hip pain.

Common causes include:

• Facet joint arthritis (osteoarthritis of the spine)
  
• Degenerative changes due to aging
  
• Injury-related joint stress
  
• Postural strain or repetitive motion over years

Conditions We Manage

If your doctor has pinpointed these areas as the likely pain source—often through a successful medial branch block—RFA may be the next step.

Diagnosis and Tests

Before proceeding with RFA, your provider will confirm the pain’s source using:

• A medial branch block (MBB) — a test injection that temporarily numbs the nerves
• Physical examination and medical history
  
• Imaging studies (MRI, CT scan, X-rays) to evaluate joint structure

If your pain improved significantly after the MBB, it strongly suggests that the target nerves are causing your symptoms—making you a good candidate for RFA.

Management and Treatment

Here’s what to expect during the radiofrequency ablation procedure:

1. Preparation – You’ll lie comfortably on an exam table. The area is cleaned and numbed with local anesthesia.
2. Guided Precision – Using a live X-ray (fluoroscopy), your doctor guides a thin needle to the target nerve.
3. Confirmation – A small electrical pulse may be used to ensure the needle is in the right spot.
4. Ablation – Radiofrequency energy heats the tip of the needle, gently burning the nerve tissue to disrupt the pain signal.
5. Recovery – You’ll rest briefly afterward, and most people go home the same day.

Most patients resume normal activity within a day or two, with full relief typically noticeable within 1 to 3 weeks.

Prevention

While RFA addresses existing pain, it also gives you a window of relief to engage in lifestyle changes that protect your spine:

• Physical therapy to build strength and flexibility
• Regular low-impact exercise (like swimming, walking, or Pilates)
• Ergonomic adjustments to your work or home setup
• Mind-body approaches, such as mindfulness or breathing techniques, to reduce tension and stress on the body

Pain relief from RFA allows many people to move more freely—something that’s key to long-term spine health.

Outlook / Prognosis

Radiofrequency ablation doesn’t permanently “kill” the nerves—they may regenerate in time—but it can dramatically reduce pain for months at a time. For some, the procedure can be repeated when the nerves grow back.

Most importantly, RFA offers something chronic pain often takes away: hope. Hope for better sleep, easier mornings, less reliance on medication, and a chance to feel like yourself again.

You deserve to feel better. If you’ve been living with unrelenting back or neck pain, and other treatments haven’t brought relief, talk to your provider about whether RFA could be right for you. It might just be the quiet your body’s been waiting for.
