Discography is a medical procedure that involves injecting a dye into the jellylike center of a spinal disc to help diagnose back problems.
During discography, a doctor looks at the amount of pressure needed to inject the dye into the disc, whether it causes pain that is the same as your regular pain, how much dye is used, and how the dye appears on X-ray after it is inside the disc.
When you've got back pain, one of the best questions you can ask is, "Why is it happening?" That can be the first step to helping the problem.
Common causes for back pain include:
Muscle and ligament injuries. These are the most common causes of back pain. Shoveling snow or helping a friend move her couch can sometimes overstretch the muscles or ligaments. You can wind up with strains or sprains. Most of these injuries heal in a few days to weeks.
Most people have changes to their spinal discs as they age, but these changes usually do not cause any symptoms.
Discography has been largely replaced by simpler and more effective methods for basic testing. It is sometimes still used in hard-to-diagnose cases or before surgery. Discography may increase the risk of having disc problems.1 Most experts no longer recommend it.2 If your doctor recommends discography, experts recommend getting a second opinion before having this test.
