As stated they can be very painfull, depending on how bad your disc are. For me the pain was extremely bad for two of my discs, but thank god they had good IV meds injected into me right away after the proceedure. As long as they have the IV meds there for you I wouldnt worry.

The discogram did give some really good information about my situation. Prior to the discogram they didnt know to what extent my DDD was causing me pain. Once the test was done, it was obvious and this information will go into the decession making of weather or not I get surgery.
