I am getting a discogram done next week. What should I expect with this procedure?

See your doctor. See your doctor to discuss what will happen during this procedure.
See below. The procedure is done to determine which disc might be causing your pain. It takes about 30 minutes to perform the test. You will be sore afterwards and should have a plan in place beforehand to deal with the pain caused by the procedure. I recommend daily massage in addition to analgesics.
