During the procedure, you lie on your stomach and receive medication to help you relax. After numbing the area, a physician uses a fluoroscope (live X-ray) to guide a cannula to the medial branch nerves. An electrode is inserted to test nerve location with a mild jolt. Once confirmed, the nerve is heated to block pain signals. Multiple nerves may be treated if needed.

After the procedure, the instruments are removed and a small bandage is applied. Some soreness is normal, and pain relief typically develops gradually over several weeks.
