A herniated disk is a condition that can occur anywhere along the spine, but most often occurs in the lower back. It is sometimes called a bulging, protruding, or ruptured disk. It is one of the most common causes of lower back pain, as well as leg pain or “sciatica.”
Between 60% and 80% of people will experience low back pain at some point their lives. Some of these people will have low back pain and leg pain caused by a herniated disk.Although a herniated disk can be very painful, most people feel much better with just a few weeks or months of nonsurgical treatment.
Your spine is made up of 24 bones, called vertebrae, that are stacked on top of one another. These bones connect to create a canal that protects the spinal cord.
Five vertebrae make up the lower back. This area is called your lumbar spine.
