Opening c6-c7, movement at c6-c7 and plate not flush ...IS THIS NORMAL

I had surgery in Nov 2009 on neck  C4-5 into first month it was fine then I went from fine to AWFUL I have badddddddddd pain ...I had a plain xray that showed a opening in disc at 6-7, plate is not flush with the c4 vertebral body and it also showed movement at c6-c7........NEXT PLAIN xray says ACDF plate is not flush with the c4 vertebral body and does show some movement with flexion at the c6-c7 space .....and she does appear to have some instability in her cervical and thoracic spine, on flextion it appears that he disc space opens at c6-c7

......THE above xrays were both on different dates and on flextion shows opening and plate not flush......a CT said completely incorporathed within the disc space however if I would not had a xray and looked down it would appear normal until I look down then it shows open space and thats when it hurts badly...........  QUESTION IS ......should plate be flush and should there be ANY opening in these disc?      I can't look down it kills me to put chin down and to lay is awful as soon as neck goes out of straight position it cause awful pain with numbness........WHAT is normal ,,,,,,,,what should I do My doctor is not being helpful at all..........I want to know why it moves and why opens when I look down and if it should do this when I look down............
