drhmom,
I had a C5-7 ACDF in April of 2006. I, too, was stubborn and afraid and waited until I was a great deal of pain and not able to do much. Afterwards, I was glad I had done it and wished I had done it sooner.
One thing the neurologist will probably point out to you is that the longer you go on with that nerve root impingement, the more damage there is to the nerve root. That means a longer recovery and the possibilty of permanent damage. You don't want to risk that just because you are afraid.
In my case, I got online and started reading everything I could about the procedure, including the stories here of people who had gone through it. At first I was pretty freaked out and grossed out by the medical part of it, but after I got used to the idea I was a lot more comfortable. I went into the morning of my surgery nervous, but not afraid.
Talk to the neurologist and ask questions. If you don't like the first surgeon you meet, go to a second one or even a third. Ask questions.
And try to start envisiong yourself in the future, feeling better.
I'll admit that recovery is not a picnic, but you do get through it. Some people get total relief and some get only a degree of relief, but I think most end up better off after than they were before.
Hope this helps a bit.
