Herniation is most common in the discs between the lower lumbar vertebrae of the spine. This is because these discs support the weight of the entire upper body. Specifically, the two discs are the L4-5 disc (which is between the fourth and fifth lumbar bones), and the L5-S1 disc (between the fifth lumbar and first sacral bones). Those two discs do a lot of work and are the ones most commonly herniated. Typically, the discs don’t take too long to heal, but professional treatment can speed up recovery. Professional treatment may even be necessary in some cases.
