I am living proof of the problems that scar tissue can cause. The pain and burning is unreal that I have. As a surgical RN i have seen scar tissue and adhesion up close. That tissue is so tough, much tougher than a disc fragment. So it should not be hard to believe that scar tissue binding the nerve root would cause significant pain. Ive had two surgeried in the past year on my lumbar spine. I have chronic pain. I just had an appointment with a neurosurgeon at cleveland clinic and she informed me that I have much more scar tissue than the norm. Then I ask all of you, what is the norm? The text book version of what each of our bodies should be. I think all health care professionals can agree that each individual and each case is unique. To say that scar tissue can NOT cause problems is unreasonable. We all need to keep an open mind to all possibilities so that our input can be of help to each other.
