I have had four neck fusions. The first three were C5-C7. In all three cases C6-C7 resulted in nonunions. I m a non-smoker and am not over weight....currently 53 years of age. In May of this year, my surgeon attempted to refuse c5-T1 posteriorly. My symptoms have never completely subsided and are starting to get worst. This time accompanied my headaches with ocular symptoms (lightening bolt type images). I can only stay in one position for 30 minutes to an hour before the pain is unbearable. Movement of my head (up and especially looking down) brings on extreme pain. I fear another nonunion. I have an appointment with my neurosurgeon on 6th Dec. what should I expect both good and bad? Thanks,
