Sorry you are here, but I hope we can help. For what it's worth, the majority of people here that require one disc replacement (or fusion for that matter) usually do well after their procedure.
I am six years post-op from lumbar ADR -- which is thought to be more challenging in terms of the procedure and the recovery -- but all is well!
Again, your situation bodes well for whichever treatment you and your medical team decide is best for you. Have you obtained all your medical records on CD? Radiologist reports? What are your next steps (besides finding a new neurosurgeon)?
