Patient Sedated The procedure is performed with the patient lying down. Intravenous sedation may be administered, and a region of skin and tissue of the neck is numbed with a local anesthetic delivered through a small needle.
Needle Inserted Using x-ray guidance (also called fluoroscopy), the physician guides a larger needle to the painful area of the neck. The needle is inserted into the epidural space, which is the region through which spinal nerves travel.
Contrast Dye Injected Contrast dye is injected into the space to make sure the needle is properly positioned near the irritated nerve or nerves.
