You will be lying on your front. Your skin will be cleaned. A small needle will be used
to inject some local anesthetic to numb the skin. This may sting for a couple of seconds.
The tip of a needle will be placed next to the spinal nerve. Fluoroscopy, an X-Ray TV,
is often used to guide the needle to the correct location. Some contrast dye may be injected
to check the exact position of the needle tip using fluoroscopy. Then the medication
will be injected around the spinal nerve, the needle removed and a small bandage placed
on the skin.
