What are some causes for a herniated disc?
A herniated disk occurs when the disc is damaged by a number of situations. Some of the most common causes of a disc injury are: * A fall or accident * Repeated straining of your back * A sudden strain on the back from lifting or twisting violently * Degeneration of the disc from aging * Spontaneous herniation can occur without any specific injury When the disc is damaged, the soft rubbery center of the disc squeezes out through a weak point in the fibrous outer layer, causing a bulge that often presses on nearby nerves. Symptoms of a herniated disc may begin suddenly or gradually. Sudden aching in the back or neck or being unable to straighten without extreme pain are signs of herniated disc problems. Numbness, tingling, or weakness in one or both arms is another sign of herniated discs. Other common symptoms of a herniated disc include: * Pain that Radiates to the Legs Pain that travels to the legs or feet may feel like a shooting pain or electric shock. This type of pain may be from
Most disc ruptures will occur when a person is in their thirties or forties when the nucleus pulposus is still a gelatin-like substance. Oddly enough, most disc herniations will occur in the morning. The causes of this phenomenon are not entirely known, but are probably due to the physiology of the spine and the changes in the water content of the disc that occur throughout the day. The two most common locations for a herniated disc in the lower back are at the disc between fourth and fifth lumbar vertebra (L4-5) and at disc between the fifth lumbar vertebra and the first sacral vertebra (L5-S1). These two discs account for 98 percent of all painful disc herniations. A herniated disc can occur elsewhere along the spine, but low lumbar herniations are by far the most common. http://www.back.com/causes-mechanical-herniated.html Well, many people want you to believe it’s old age, excess weight, stress, poor
Causes Disc herniation’s can occur from general wear and tear, such as jobs that require constant sitting, but especially jobs that require lifting. Traumatic (quick) injury to lumbar discs commonly occurs from lifting while bent at the waist, rather than lifting while using the legs with a straightened back. Minor back pain and chronic back tiredness is an indicator of general wear and tear that makes one susceptible to herniation on the occurrence of a traumatic event from bending to pick up a pencil, or heavy backpack from the floor. When the spine is straight, such as standing or lying down, internal pressure is equalized on all parts of the discs. While sitting or bending to lift, internal pressure on a disc can move from 17 psi (lying down) to over 300 psi (lifting with a rounded back).Smoking is a major risk factor as the chemicals within smoke cause diminished nutrition and oxygenation of the discs leading to dehydration & degeneration which can then proceed to herniation.
