YES ! i had c4-7 fused, And had the exact same symptoms. I've been to many Dr's and specialists since. Everything seems to come back normal. However, I have a GREAT pt. Over the past few years of seeing all these symptoms, just recently he took me thru kind of a eye test, seeing if my eyes and brain are tracking together. As well as he has me doing new exercises at home. Since my surgery, and my body trying to compensate for everything that's changed, my neck posture has changed which definitely can produce these symptoms. I seem to have more forward neck positioning than ever before. I'm doing a exercise trying to retrain my neck muscles to go back to normal, and it has helped. I don't know if this can help you, but HOPE so, cause it's miserable.
