This injection targets a painful nerve in your spine. It helps your doctor find which nerve is pressed on by a herniated disc, spinal stenosis or some other problem. It may give you pain relief.
To begin, you lie down. You may be given medicine to help you relax. You are numbed with an injection of local anesthetic.
Next, a needle is inserted through this numbed tissue. The doctor uses a fluoroscope (a video x-ray device) to guide the needle into the space around your inflamed nerve. The doctor may inject contrast dye to make sure the needle is in the right place
Finally, the doctor injects the medicine. It bathes the target nerve. If your nerve is inflamed, it can relieve pain and swelling.
