@dablues You do have a significant amount of multilevel cervical issues causing spine related symptoms. You might also want to consider a neuro-opthalmologist because of the double vision. Here is a link that explains some of the things that neuro-opthalmologists address. It has an overlap with neuro-surgery. According to this Mayo article, there are few of these specialists, but Mayo has them on staff. I think it would be to your advantage to work with an interdisciplinary team that can address all the issues. It sounds like your current specialists don't know what is causing the double vision, and that can be a source of uncertainty for your doctors. I hope this is of value.
