The patient is placed on an exam table face down, they are often sedated. Their vital signs are monitored and the area to be injected is first cleansed with antiseptic solution, and then numbed with a topical anesthetic to ease the sensation of the insertion of the needle.

The doctor uses a device called a fluoroscope, (a type of xray machine that allows them to see the needle being inserted in real time) to insert the needle in order to minimize the risk of damaging tissue or nerves with the needle and ensure proper needle placement.

Contrast dye is often used to determine that the medications will contact the nerves desired and then the medications are slowly injected.
