Thank you for your question.
One of the reasons for persistent pain is pseudoarthrosis or nonunion at the attempted fusion site. Stenosis is narrowing of the spinal canal
that predisposes to paralysis
. If that is the case documented on your MRI you will need to see a spine surgeon
as surgery is indicated in that scenario. A CT scan of the cervical spine
can diagnose the nonunion. It can be effectively treated with surgery which is a last option if pain is the only complaint and it is not effectively controlled with pain management modalities..
