Your doctor wants you to have a lumbar discogram. This test looks for problems in the disc area.
The discogram will be done by a radiologist. It will take about 1-2 hours to complete. First, we numb your skin. We place a thin needle into some of your lumbar discs. We put a liquid with iodine into the disc area to confirm placement of the needles. We will then ask you if you are feeling pain in your back.
After the test, many patients report more low back pain. You may need more pain medicine after this test. The pain may also limit what you can do for a few days.

You need to have an MRI or CT scan of your lower spine.
You must weigh less than 420 lbs.
Do not eat for 2 hours before your test. You may have water to drink.
You may take your usual dose of pain medicine the morning of the test. Do not repeat the dose before the test. This may affect the results of the test.
Please bring your pain medicine with you. You may take it after your test, if needed.
You must have someone drive you home after your test.
