A herniated disc, or spinal disc herniation, is a condition that occurs due to a problem within one of the discs (rubber pads) in the cervical vertebrae, which separates the vertebrae of the spine. These discs are like a filled donut disc, as they consist of an outer, frame-like strip called the annulus fibrosus containing a gel-like substance, called the nucleus pulposus. And with enough pressure on these discs, the inner gelatinous content of the disc may burst through cracks or weaknesses in the outer shell, which leads to the inflating of the weak fractured part as a balloon that appears to come out from between the vertebrae to compress the nerves in the spinal tunnel,Or that the nucleus pulposus leaks through a rupture of the outer envelope of the disc.
