Bad Back - Degenerative Disk Disease.

I’m thinking of having back surgery for a non-descript “DDD” which stands for Degenerative Disk Disease. I have researched the internet including some “scholarly” articles, and I come to the conclusion that the success rate (meaning most of the pain goes away and you don’t have a repeat operation in 1 to 4 years) is between 30% and 70% - not great odds in my opinion. Can anyone comment on this with their experience - either good or bad. Thanks, Jerry
