Failed back surgery
syndrome is characterized by severe symptoms post-spinal surgery. Often the patient may not have been the right candidate for spinal surgery in the first place.
Other impediments to recovery from back surgery include recurrent or residual disc herniation
or a failure to fully correct the structural source of pain during surgery. Epidural fibrosis, a build up of scar tissue around the spinal nerves, is common post-surgery, but not a direct cause of failed back surgery syndrome.
