Why do some people continue to have pain after back surgery?
There are many reasons. Sometimes after surgery scar tissue or adhesions can form. This can cause pain by pinching or pushing on the nerve tissue in the back. Also, some surgery can cause adjacent areas of the back to degenerate or weaken over time. The spine is a very complex network of ligament, muscle, bone and nerve tissues all of which may cause pain due to injury alone or in combination with each other.
