Determining the age of herniated discs is a very specific matter that depends upon the history, quality, intensity of pain, prior imaging and medical records. This is called a “medico-legal determination” and some doctors are better than others in the elucidation of this timeline. Unfortunately, some doctors in this legal field have a predetermined mindset which makes these matters more difficult to determine causation. I cannot tell you who is better in this field than others.
