It is distinctly uncommon to have any significant pain in a well working ADR. Motion at C6-7 was probably limited before the ADR and that could have been one of the reasons for failure (if that is even the presenting problem). You can use the flexion-extension films now (you need them) and measure the current motion of C6-7. That will give you an idea of any loss of motion but i expect you have little to no motion at that level now if the disc has failed.
