Chronic low back pain can be due to a herniated disc
Herniated disc is not a common problem, occurring in 1 out of 900 people. It is an abnormality related to the intervertebral discs which may be slipped, ruptured, bulging, or herniated. This generally affects the lumbar region of the spine, causing pain in the lower back area.
1 What is spinal disc herniation?
Each disc in your spine acts like cushion between two spinal bones (vertebrae). The spinal disc is made up two layers: the soft and squishy inner core referred to as the nucleus; and the tough and hard exterior protecting the nucleus outer called the annulus fibrosus. A herniated disc is a condition wherein the tough outer wall of the disc ruptures and the soft nucleus flows out, deforming the shape of the disc.
