Most people are back to light activity within a day or two after radiofrequency ablation (RFA), but the pain relief itself builds more slowly. It's normal for your back to feel sore, or even a little worse, for the first week or so. Relief usually shows up within about three weeks, once the treated nerves stop sending pain signals.
TL;DR Medical Summary: After radiofrequency ablation, expect soreness at the needle sites for a few days and possible sunburn-like sensitivity for one to two weeks. Most people resume light activity within a day or two. Relief usually builds over two to three weeks and typically lasts four months to a year.
How long does it take to recover from radiofrequency ablation?
Most people return to light daily activities within one to two days, and the treated area may stay sore for about one to two weeks. Full pain relief usually takes two to three weeks, because the treated nerves need time to stop sending signals.
There's no incision to heal, so recovery is mostly about managing short-term soreness. If you're still deciding whether RFA is right for you, start with our patient guide to facet joint pain and radiofrequency ablation.
What does the RFA recovery timeline look like?
Soreness peaks in the first few days and fades over one to two weeks, while relief builds over two to three weeks. Here's what a typical recovery looks like.
| Timeframe | What you may feel | What helps |
|---|---|---|
| Day of the procedure | Numbness wears off over a few hours; soreness at the needle sites | Rest at home, use ice if your care team recommends it, and follow your written instructions |
| Days 1 to 3 | Muscle soreness, tenderness, or a short flare of your usual pain | Light walking and normal daily tasks; hold off on heavy lifting and hard workouts |
| Days 4 to 14 | Soreness fading; some people notice a sunburn-like sensitivity over the treated area | Stay gently active and ease back into your routine |
| Weeks 2 to 3 | Relief usually becomes noticeable | Start or resume physical therapy or a strengthening routine if your care team recommends it |
| Months 4 to 12 | Relief typically lasts in this window; some pain may slowly return as the nerves regrow | Let the office know when your pain starts coming back |
What should I do the first day after RFA?
Plan to rest for the rest of the day and take it easy. The numbing medicine wears off over a few hours, so some soreness at the needle sites is expected.
- Use ice on the area, about 20 minutes at a time, if your care team recommends it.
- Take only the pain relievers your care team has approved.
- Keep the small bandages clean and dry, and follow your written aftercare instructions.
- If you had sedation, you'll need an adult to drive you home, and you shouldn't drive for the rest of the day.
Is it normal for back pain to feel worse after RFA?
Yes. A short-term flare in the first week or so is common as the nerves and surrounding tissue react to the treatment, and it doesn't mean the procedure failed.
Some people also feel a sunburn-like sensitivity or brief burning over the treated area. This usually fades within one to two weeks. Less often, the treated nerve becomes irritated (called neuritis), which can cause a burning pain that lasts a few weeks before settling. Studies of lower back RFA report this at fewer than 1 in 10 treated nerve sites.
When will I feel relief after radiofrequency ablation?
Relief usually becomes noticeable within two to three weeks. Some people feel better sooner and a few take longer, so try not to judge your results in the first week.
Soreness from the procedure can also mask the relief underneath. If you don't notice any improvement after about six weeks, schedule a follow-up so the care team can reassess what's causing your pain.
What activities can I do after radiofrequency ablation?
Most people can walk and handle light daily tasks the next day, and many return to desk work within a day or two. Hold off on strenuous exercise and heavy lifting for the first few days, then build back up gradually.
Usually fine right away:
- Walking and light household tasks
- Desk work or other light duties
Wait until soreness settles and your care team says it's okay:
- Heavy lifting or yard work
- Intense workouts, running, or contact sports
- Physical jobs that involve bending, twisting, or carrying loads
How can I make RFA relief last longer?
Use the lower-pain window to rebuild strength and mobility. Relief typically lasts four months to a year, and staying active helps protect your results.
- Follow through with physical therapy or a home exercise plan. Strengthening your core and back muscles supports the spine and the facet joints.
- Notice when pain starts coming back. In Dr. Serpa's experience, many patients begin to feel some pain return around four to five months after treatment, while others go a year or longer.
- Plan ahead. Because the treated nerves slowly regrow, RFA can usually be repeated if the first treatment worked well. Calling the office early helps you avoid a long gap in relief.
When should I call the doctor after RFA?
Most soreness after RFA is normal, but some symptoms need prompt attention. Call the office right away if you notice signs of infection or new nerve problems.
- Fever or chills
- Redness, swelling, warmth, or drainage at a needle site
- New weakness or numbness in a leg
- Severe pain that keeps getting worse instead of better
Call 911 for loss of bowel or bladder control or any other medical emergency.

Frequently asked questions
Soreness at the needle sites usually eases within a few days, and deeper muscle soreness or sensitivity can last one to two weeks. If your pain keeps getting worse instead of better, call the office.
Many people return to desk work or light duties within a day or two. Jobs that involve heavy lifting or physical labor may need a few more days, based on how you feel and your care team's guidance.
A burning or sunburn-like feeling over the treated area is a common, temporary reaction as the treated nerves settle down. It usually fades within one to two weeks, though nerve irritation can occasionally last a few weeks.
Possibly. The treated nerves slowly regrow, so relief typically lasts four months to a year, and RFA can usually be repeated if the first treatment worked well.
