What is radiofrequency ablation (RFA), and how long does relief last?

Quick answer: Radiofrequency ablation (RFA) is a minimally invasive, outpatient procedure that uses heat from radio waves to interrupt pain signals from specific nerves. Most patients get lasting relief from chronic back, neck, or joint pain, often six months to two years, without surgery.

How RFA works

Using live imaging for precision, a thin needle is guided to the nerve causing your pain. Radiofrequency energy then creates a tiny, controlled lesion that interrupts the pain signal traveling to the brain. You stay awake under local anesthesia and go home the same day.

What it treats

• Chronic lower back and neck pain
• Arthritic knee and hip pain
• Facet-joint pain from wear and degeneration

Recovery and how long relief lasts

Downtime is minimal, most people resume normal activity within a day or two. Relief typically lasts between six months and two years, and because nerves can regenerate, the procedure can be safely repeated when pain returns.

Frequently asked questions

Is radiofrequency ablation painful?

The procedure is done under local anesthesia; most patients feel only mild soreness for a few days afterward.

How long does RFA relief last?

Commonly six months to two years, and it can be repeated when pain returns.

How soon will I feel relief?

Some patients feel better within days; the full effect often develops over a few weeks as the treated nerve settles.

If injections or therapy haven’t given you lasting relief, RFA may be the next step, and we can tell you whether you’re a candidate. Schedule a consultation with Illinois Pain & Spine Institute: call (800) 340-7246 or book online here.
