Radiofrequency Ablation Recovery and Aftercare

Radiofrequency ablation (RFA) can quiet the small nerves carrying pain from an arthritic spine joint — often for many months. But the recovery has a twist that surprises people: you may feel a bit sore at first, and the real relief usually arrives a little later. Knowing what to expect, day by day, makes the whole process smoother. Here’s the aftercare guide.

Right after the procedure

RFA is done as an outpatient procedure, so you head home the same day — but arrange a ride, since you shouldn’t drive right afterward. It’s common to feel sore or have some muscle spasm at the treatment site for a few days, and a temporary bump in your usual pain as things settle. Cleveland Clinic notes that “you may still feel soreness, pain or muscle spasms at the treatment site for a few days” (Cleveland Clinic). This early soreness is expected and eases on its own. If RFA is new to you, our overview of radiofrequency ablation explains how it works.

When pain relief begins

Here’s the part worth understanding up front: RFA relief is usually not instant. Some people feel better quickly, but for many, relief builds gradually over the first ten days to three weeks as the treated nerve stops sending pain signals. So if you’re still sore in the first few days, that doesn’t mean it didn’t work — give it time to take effect.

Aftercare: the first days

A few simple steps help you recover comfortably:

• Rest the day of the procedure and avoid strenuous activity and driving for about 24 hours.
• Use ice on the treatment site — about 20 minutes at a time — for the first day to ease soreness.
• Ease back in. Most people return to normal activities, including bathing, within a day or two.
• Take medication as directed if your doctor prescribed anything for the initial soreness.
• Do your physical therapy if it’s recommended, to rebuild strength and flexibility once the pain settles.

How long relief lasts

When RFA works, the relief tends to last a good while — commonly 6 to 12 months, and sometimes longer. The treated nerve can slowly regrow over roughly 6 to 12 months, which is why pain can eventually return — and why the procedure can be safely repeated when it does. Many people settle into a rhythm of periodic RFA that keeps their spine-joint pain manageable. Our guide on how long RFA lasts for back pain goes deeper on this, and because RFA targets the facet joints, our guide on medial branch blocks vs. facet injections explains the diagnostic step that usually comes first.

Side effects and risks

RFA has a strong safety record. Cleveland Clinic notes that “the risk of complications from RFA is very low” (Cleveland Clinic). The common experiences are temporary: soreness, a small area of numbness, or a mild burning sensation that fades over a week or two. More serious problems like infection or bleeding are uncommon. Your care team will go over what’s normal and what isn’t for your specific case.

When to call your doctor

Most recoveries are uneventful, but call your care team if something seems off.

Frequently asked questions

How long does it take to recover from radiofrequency ablation?

Most people return to normal activities within a day or two, though some soreness or muscle spasm at the site can last a few days. Strenuous activity and driving are usually avoided for about 24 hours.

When will I feel pain relief after RFA?

Relief is often not immediate. Some people feel better quickly, but for many it builds over the first ten days to three weeks as the treated nerve stops signaling pain. Early soreness doesn’t mean the procedure didn’t work.

How long does radiofrequency ablation last?

Relief commonly lasts 6 to 12 months, and sometimes longer. Because the treated nerve can regrow over time, pain may eventually return — and the procedure can be safely repeated when it does.

What should I avoid after radiofrequency ablation?

Avoid strenuous activity and driving for about 24 hours, and ease back into your routine over a day or two. Follow any specific instructions from your care team, and use ice on the site to help with early soreness.

Is radiofrequency ablation safe?

Yes — RFA has a very low rate of complications. Side effects are usually temporary, like soreness, a small area of numbness, or mild burning that fades in a week or two. Serious problems such as infection are uncommon.
