I must admit: I'd go with what I know about my body (how it has been - past v. present) in conjunction with what films, symptoms and exams indicate.

If C.E. is "on the table" (so-to-speak), I'd definitely want to know that and also from more than one specialist. I know that you know that, too; I detect it from reading your post.

As long as "things" are already exposed, I'd also get the spur(s) removed. No sense leaving 'em inside.

I only wish you the best, as I'm sure others do/will as well.

Confidence not only in the procedure but the surgeon operating: Essential.

Even if at the last moment before any surgery that you may want to delay, just please listen to your inner-voice; it's there for a good reason .
