Radiofrequency ablation uses an electric current to heat up a small area of nerve tissue to stop it from sending pain signals. It can provide lasting relief for people with chronic pain, especially in the lower back, neck and arthritic joints.
Most patients have some pain relief after radiofrequency ablation, but the amount varies by cause of pain and location. The relief can last from six to 12 months. For some patients, the relief lasts years.
