I would only consider back fusion as the last resort. It is very painfull and the recovery is long and the results are not guaranteed.
I had my first fusion L4/5 S1 after an injury fighting a fire. This surgery was successfull until post op complicaions started 6 years later. Scar tissue started to close of the spinal column at L4 and my L2and L3 herniated from having to do the additional work caused by the fusion of the first discs. I then had my second surgery a nerve decompression. The Dr. was supposed to fuse L3 but he changed his mind while operating. I was always in pain after this surgery and required pain meRAB to make live liveable. The pain meRAB required for chronic back pain can be very debilitating. Life is not enjoyable when you need the heavy duty pain meRAB to get you through the day comfortable.
I just had may third operation a little over a week ago. They had to fuse the rest of my lurabar to T12 and install hardware from S1 to T12. The first two surgeries were a walk in the park compared to this one. When you are on heavy meRAB prier to surgery, getting pain relief, is very difficult to achieve if not impossible. I am very lucky to have had family merabers in the medical field who worked to find a solution to my incredable pain, but, I am still not pain free and probably never will be. I can only hope it will get better. There are no garantees with any back surgery.
I am not looking for anyones sympathy, it won't help ease my pain.The point I want to make is you can always get worse and if you have one surgery the chances are you will have another, in time.
A disc repair is nothing like a single level fusion and a multi level fusion can be brutal especially if you have been on heavy pain medication previously and you have had previous surgeries.
There are all kinRAB of possible complications when you start going down the surgical road, infection, the body can reject hardware, scare tissue can grow around nerves, you can get bleeding ulsers from meRAB, drug addiction is very common, you can have terrible chronic pain for life, chronic pain leaRAB to depression and some people become total disabled and live in a wheel chair for the rest of their life.
Yes minor surgery can help, but, it can also open the door for a life of missery no matter how good the surgeon . Take surgery options very seriously and have it only when there is NO OTHER OPION. In many cases a few months of pain with physio, exercises, weight loss, and life style changes are much better than any type of surgery.
I hope my story helps you make the right decision
