The cervical spine is the upper part of the spine comprising of the first 7 vertebrae. The vertebrae are separated from one another by shock absorbing pads called intervertebral discs. Over time, these natural shock absorbers wear out and degenerate due to aging, trauma or injury. As a result, the space between the vertebrae narrows and nerve roots can get compressed resulting in neck pain. This is also known as cervical degenerative disc disease (DDD).
Traumatic injury, postural strain, repetitive movements, overuse, changes in posture or poor body mechanics and being overweight may alter the structure of the disc. All of these structural changes can place abnormal stress to the cervical spinal roots resulting in pain.
