What are the long term complications with a Cervical fusion of c3 to c6(4 levels)?
I am having a lot of pain above and below the fusion site the worst being the lower right side. My second question is, could this pain be from an over extension of the ligaments or discs at c6-7, c7-t1, t1-2. Or are there other possibilties ( I am sure there are many but I would like to know the most likely.
