i had a three level acdf in september 06 with titanium plate and cage. i am in worse pain and limitations than before surgery. my neuro had xray, ct scan and mri and see that one of the fusion failed and the disc below the fusion is bulging but not bad enough for the pain that i am feeling. he can't figure out why i am hurting so bad. like you i am so frustrated.i cry because it seems like i am in so much pain and no one to help or believe me. i work but have a lot of restrictions but i don't know what to do. i thought of second opinion. i have all of the symptons problems that you are having. i hope you can find relief. keep in touch and let me know what happens.
