What happens during radiofrequency ablation (RFA)?

ANSWER

You'll get local anesthesia to numb the area. Then the doctor will insert a small needle into the affected area. Using X-ray, your doctor will guide the needle to the exact target area and insert a microelectrode to start the stimulation process.

During the procedure, your doctor will ask if you can feel a tingling sensation.

Once the needle and electrode placement are set, your doctor will send a small radiofrequency current through the electrode into the surrounding tissue, heating it up. It shouldn't hurt.
