A Herniated Disc L4 and L5 is when a disk in the spine ruptures. If you look at the picture to the top right of this page, you can see an illustration of different back issues. A bulging disk is simply a disk that is inflamed and is bulging outward of the spin. When that bulging disk in the L4 and L5 area becomes so severe, it can rupture and become a Herniated Disc L4 and L5.
Why is this such a big deal? From continuous abuse of the spine either due to growing older, sports, or even just genetics, the disk in the spine can start to deteriorate. When this happens, the disc can bulge and then herniate. The typical area for this to happen is in the lumbar spine herniated disc l4 and l5. When it bulges or herniates, the disk touches the nerves on the spine and creates a situation called a pinched nerve. This pinched nerve in the Herniated Disc L4 and L5 region can cause severe pain and numbness in the lower back, legs, behind, and foot.
