The patient is then asked whether or not the fluid is causing pain. If it is producing pain, the next question is whether or not the pain being experienced is the same as that occurring on a daily basis.
If it is the same, that represents a positive study. If the patient states that he or she does have pain from the procedure but it is different from that experienced on a daily basis, that is not a positive result. Of course, if the discogram causes no pain it’s a negative study as well.
Typically, the Pain Doctor in Las Vegas will also perform the discogram at a control level, which is a disc level that is not suspected of contributing to a patient’s pain. If the control level is positive, then it may be that the patient is either not being truthful, or it is possible that it is not really a control level at all but a pain contributor.
