An injured disc can be a source of pain. A discogram is an X-ray procedure used to determine if a particular disc is the source of pain. Discograms are provocative tests, meaning that they attempt to reproduce a problem rather than remove a pain. The reproduction of pain during a discogram can help the doctor determine if injury to a particular disc is the source of a person’s pain.
During a discogram, a needle is inserted into the disc, and a contrast dye is injected. This extra fluid in the disc increases the pressure in the disc. Patients with an injured disc may then experience pain that can mimic the pain they have been experiencing. The intensity of the pain is recorded on a 0-10 scale.
Patients may be sore for several days after the procedure. Any discomfort can be treated with the local application of ice packs or with a cooling pad on and off for periods of 20 minutes.
Because it is an invasive procedure, a discogram carries some risk of infection as a complication. This risk is shallow as it is performed under sterile techniques. The discogram could also cause an injured disc to worsen and cause more symptoms.
