Herniated Cervical Disc

Bursting of cervicalintervertebral disc which generally casts material posteriorly into the region of the neck usually reserved for nerve roots. This can press on the nerve roots or bring about an inflammatory reaction, both of which can activate fibres within or at the surface of the nerve roots, causing pain, paraesthesias, numbness and muscular weakness in the cervical spine and the upper extremities. In some cases, where the herniated disc is in the center, the disc material can actually affect nerves destined for the lower extremities and pelvic floor, causing hyperactive reflexes as well as the other symptoms mentioned above, and even incontinence.
