Sandwiched between each of the vertebrae in your spinal column is a disk of cartilage that acts as a shock-absorbing pad. These disks have a soft, jellylike center and a tough, fibrous outer layer. A tear in this outer layer will allow some of the soft center to bulge out. This bulge on the nerve roots emerging from the spine in the region of the damaged disk.

CAUSES
Any activity that puts increased pressure on the disks of your spine can lead to a disk hemlation.This can occur in the cervical spine, or, more commonly in the lower back. He general gear and tear that comes with age can also contribute, making middle-aged people susceptible to if they bend suddenly or lift an awkward weight.

SYMPTOMS AND DIAGNOSIS
Depending on the location of the herniated disk, symptoms can vary, but there is usually severe pain and restriction of movement. In the lower back, the pain tends to be a deep unrelenting ache, which may radiate out to your hips; groin buttocks and legs. You may also develop sciatica-a sharp pain, radiating down one leg accompanied by numbness or tingling. Herniated disks can also occur in the neck, causing severe pain that may spread into your shoulders, arms and hands, making it difficult to turn your head or move it backward or forward. You will usually feel pain in only one side of your body. Your doctor will make a diagnosis by performing a physical examination; if your symptoms persist, he may order further tests, such as an MRI or CT scan.

RISK AND DISCOVERY
Recovery from a slipped disk usually takes 4-6 weeks .However if a disk herniated protrudes fully into the spinal curial; it can compress the caudal equine and damage the nerves leading to your legs, bladder and Bowles. This may result weakness and numbness in both legs and the lower part of your body, loss of bladder and bowel control, and even impotence. Although this rarely happens, it is an emergency and you should seek immediate medical help.
