I could use some feedback from anyone who has had cervical fusion.

Hi. I’ve had a spinal fusion from T11 on down to S1 one year ago. I still have leg weakness and balance issues. My surgeon has been giving my cervical spine in the area of C6 and 7 the stink eye for over a year and stated that my leg and balance issues, more than likely, are due to that area being narrow. He would go through the front of my throat. Help me out understanding how well this usually goes and what discomfort I will experience. This surgery just seems creepy to me.
