Radiofrequency Ablation (RFA)

What Is Radiofrequency Ablation?

Radiofrequency ablation — RFA for short — is a minimally invasive procedure that uses heat to interrupt the nerve signals that are sending pain messages to your brain. Think of it this way: if a nerve is like a phone line carrying a pain call to your brain, RFA temporarily disconnects that line so the call can't get through.

The nerve isn't removed — it's gently heated so it stops transmitting pain. Over time, the nerve slowly regrows, but many patients enjoy months of significant relief before that happens.

Am I a Candidate for RFA?

RFA works best for patients who have already had a positive response to diagnostic nerve blocks — those are test injections where Dr. Patibanda numbs specific nerves to pinpoint exactly where your pain is coming from.

If those test injections gave you noticeable relief (even if it was temporary), that's a strong sign that RFA can give you longer-lasting results. It's like confirming the diagnosis before committing to the treatment.

RFA is commonly used for:

  • Facet joint pain in the neck or back
  • SI joint pain in the lower back and pelvis
  • Chronic pain that hasn't responded well enough to injections or physical therapy alone

What Happens During the Procedure?

The procedure typically takes 30–60 minutes, depending on how many nerves are being treated. Here's what to expect:

  1. You'll lie face down on a comfortable procedure table
  2. Your skin is cleaned with a sterile solution and the area is numbed with a local anesthetic — a brief pinch and sting
  3. Dr. Patibanda uses fluoroscopy (real-time X-ray guidance) to place thin, specialized needles next to the target nerves
  4. A small test is performed — a mild electrical current helps confirm the needles are positioned correctly, away from important nerves you need for movement. You may feel a tingling or buzzing sensation — this is normal and actually helpful
  5. The area is numbed again for your comfort
  6. Radiofrequency energy is applied — each nerve is heated for about 60–90 seconds. You may feel warmth or pressure, but the numbing medication keeps you comfortable
  7. The needles are removed, small bandages are placed, and you're finished

Most patients are surprised by how manageable the procedure feels.

How to Prepare

  • Medications: Let us know everything you take. Blood thinners may need to be paused — Dr. Patibanda will give you specific instructions
  • Eating: You may eat normally unless instructed otherwise
  • What to wear: Loose, comfortable clothing
  • Bring a driver: You'll need a ride home. Plan to take it easy for the rest of the day

Recovery: What to Expect

Recovery from RFA is a bit different from a simple injection — here's an honest timeline:

Days 1–5: The Sore Phase

You'll likely feel sore or achy at the treatment sites. Some patients describe it as feeling like a sunburn deep in the muscle. Ice packs, gentle stretching, and over-the-counter pain relievers can help. Take it easy — no heavy lifting or intense exercise.

Weeks 1–2: The Transition

Soreness fades gradually. You may notice your original pain starting to decrease, or it may still feel about the same — this is normal.

Weeks 2–4: The Relief Phase

This is when the full benefit typically kicks in. As the treated nerves stop functioning, pain signals quiet down. Many patients describe this as a “turning point.”

Months 1–18: Sustained Relief

Most patients enjoy 6 to 18 months of significant relief. The nerve will slowly regenerate over time. The good news: RFA can be repeated, and it often works just as well the second or third time.

Risks and Benefits

Benefits

  • • Long-lasting pain relief (typically 6–18 months)
  • • Minimally invasive — no incisions, no stitches
  • • Can be repeated when the nerve regrows
  • • Often reduces or eliminates the need for pain medications
  • • Gets you back to activities you've been missing

Risks (uncommon)

  • • Soreness or muscle spasms at the treatment site for several days
  • • Temporary numbness or skin sensitivity near the treated area
  • • Infection — very rare with sterile technique
  • • Nerve damage affecting movement — extremely rare

When to Call Our Office

Reach out if you experience:

  • Fever or chills after the procedure
  • Pain that gets significantly worse after the first week instead of improving
  • New weakness in your arms or legs
  • Signs of infection — increasing redness, swelling, warmth, or drainage at the treatment sites
  • Anything that concerns you — we'd always rather hear from you

Frequently Asked Questions

How long until I feel better?

Most patients begin to notice meaningful improvement 2–4 weeks after the procedure. The first few days may actually be more sore than usual — that's expected and temporary.

How long does the relief last?

Typically 6 to 18 months. Every patient is different. When pain returns, the procedure can be repeated.

Can I drive myself home?

No. Please bring a driver. You can usually resume driving the next day.

Will it hurt?

Dr. Patibanda numbs the area thoroughly before treating the nerves. Most patients feel pressure and warmth, but the procedure is well-tolerated.

What if the nerve blocks didn't help?

If the diagnostic blocks didn't relieve your pain, RFA is unlikely to help for that specific area — and that's actually useful information. It helps Dr. Patibanda narrow down the true source of your pain.

Can the nerve grow back?

Yes, and that's actually by design. The nerve regenerates over time, which is why the pain may eventually return. But it also means the procedure is safe to repeat.
