Thanks so much for replying, dianaandbill, I hope all the pain you are experiencing will be very short lived and may you have a speedy healing process.
It has been well over a year since my dad's c1-2 fusion and his pain is just as bad as ever

.
He had returned to the orthopedist that performed the surgery and was told that there were no problems, the pain should go away as the bones knit in some more. The orthopedist then referred him to a neurologist (who just happened to be a patient of said orthopedist, having undergone a successful fusion surgery himself). The neurologist said that there was no physical cause for the pain, and it certainly could not be the result from the fusion surgery!
At this point, my father has been told by these two doctors that "nothing more can be done, just go back to work/deal with the pain as best you can". He should have taken disability years ago (all of his doctors at the time were pushing him to), but he flat out refused to in favor of working until retirement. He still continues to work with the incredible pain in his head. It had gotton so bad that he mentioned retiring early on disability to the orthopedist, and the dr said, "There's nothing wrong with you that you can't go to work every day," - this is among a myriad of other physical problems that leave him completely debilitated at times.
It's been suggested my father see another doctor, but all the specialists in his area either won't see his case and refer him to the dr that did his surgery, or they have already seen and referred him. It makes me so mad to see him suffer, and he's afraid if another doctor would find something wrong they would have to do another surgery (sigh).
I hate to have frightened anybody, but I don't feel it can be said enough that with this kind of surgery to get
several opinions from
completely unrealted doctors that are far enough away from each other to not have any conflicting interests. Regards.
