(Below has nothing to do with people who need surgery due to catastrophic injury or congenital defect.)
Most surgeries are followed by more surgeries.
And the hard truth is that most surgeries happen because most people do not have the discipline to do what's needed over many months to solve the problems they are having with the chronic pain they are in. They want a faster solution and are never really told by anyone that the only real permanent solution is one that will be difficult and take months.
Rather than change their habits and their environments and their bodies, people opt to do things that have surprisingly low rates of success and more often than not result in a state than can never be fixed.
Some people get past the point of no return. For those people, surgery may be the only option. But for most people the only real option is a change in lifestyle that is more or less like deciding you are going to get very fit. It takes months and in the mean time, theres a lot of effort and discomfort.
In addition, most people don't really get how much of their back pain and ailment is due to ergonomics. That their bed is wrong. That they are sitting in a bad office chair or couch.
But more than that, most people don't get how central exercise and core strength are for maintaining the health of your back.
So before you get back surgery, consider getting a new office chair, exercising more, and facing that pain for a few more months. Work toward a real solution.
