Surgery for A.S.

I want to hear from all of you who have had A.S. related back surgeries. I have already had a fusion and now it appear's that I have a huge bulging disc right above that. I will talk to the Rheumatologist on Monday to see what is up. Probably have the neck and upper back to look at as well. Should I just have the rod's done now or wait? Who has waited and who went pro-active and got it done early?
