PROLAPSED INTERVERTEBRAL DISC(SLIPPED DISC)

When you have a prolapsed disc (which is commonly called a "slipped disc") what happens is that part of inner softer part of the disc bulges out through a weakness in the outer part of the disc.A prolapsed disc is therefore sometimes called a herniated disc.Thebulging disc may press on nearby structures such as a nerve coming from the spinal cord.Some inflammation also develops around the proladsed part of the disc.Any disc in the spine can prolapse. However,most prolapsed discs occur in the LUMBAR part of the spine(lower back).The size of prolapse varies.The larger is the prolapse,the more is the severity of symptoms.
