OverviewThis procedure, also called a "discogram," helps your doctor find painful spinal discs. It can show the source of pain in your back. To see how it works, let's watch a discography done in the lumbar spine.
PreparationTo begin, you lie down and you are given medicine to help you relax. You will still be awake. That's so you can tell your doctor what you feel during the procedure. Your lower back is numbed with local anesthetic.
Placing the NeedlesThe doctor uses a video x-ray device called a "fluoroscope" to carefully guide a needle into the target disc. If more than one disc is being tested, a needle is placed into each one.
End of Procedure and AftercareWhen the procedure is done, the needles are removed. Before you leave, your doctor may want to get a more detailed scan of your discs. Discography can cause your back to be slightly sore for a few days. Your healthcare provider will give you tips to help ease this minor pain.
