I represent a lot of people who injure their backs.  Many of those individuals end up with something called a herniated disc.  It is amazing to me that there is so little explanation to my clients of what a herniated disc is and how to treat it.  This lack of information can lead to confusion and a lot of unnecessary fear.  There is an easy to understand overview of herniated discs and corresponding treatment at the following link:   http://www.nlm.nih.gov/medlineplus/herniateddisk.html.
