Based on your experience it seems like a Marcaine injection alone is a diagnostic for discogenic pain. Did the doctor inject it into the soft center of the disc through the syringe/catheter that was used to pressurize the disc? They say there isn't very good blood flow in the fiberous portion of the disc. Did it take a while for the Marcaine to kick in and did the pain relief last longer than lidocaine injections elsewhere in the body? Just curious.
