It may result in back pain, pain or abnormal sensation in different parts of the body, and physical disability. The most conclusive diagnostic tool for disc herniation is MRI, and treatments may range from painkillers to surgery. The risk of disc herniation may be reduced by maintaining core strength and an awareness of body mechanics including good posture. When a tear in the outer fibrous ring of an intervertebral disc allows the soft, central portion to bulge out beyond the damaged outer ring, the disc is said to be herniated. Disc herniation is frequently associated with age-related degeneration of the outer ring, known as the annulus fibrosus, but is normally triggered by trauma or straining from lifting or twisting. Tears are almost always posterolateral (on the back sides) owing to relative narrowness...
