Lumbago - Sciatica - Backache

Lumbago is often provoked by banal causes, i.e. a muscular or ligaments’ sprain, that may occur after a bad movement (as a fall), or after having lifted heavy weights or having done an exaggerated physical effort.

Obviously inadequate training, a wrong posture, overweight together with many other factors can help the happening of the problem.

Other causes source from the spine itself: lumbago may descend from an arthritis of the spine (spondylosis) degenerative arthritis of the spinal vertebrae and related tissue; on the vertebral surface they may form the so called osteophytes (bony projections) that sometimes impinge on nerves causing pain.

Spine arthritis often shows up together with a problem of the intra vertebral discs that tend to become more thin. This causes the vertebrae to come closer with a consequent reduction of the space left for the nerve roots.

The result is an irritation of the nerve structures that causes a lumbar sciatica. Another possible cause of compression of the nerve’s root is spinal disc herniation, main factor of sciatica.

Lumbar sciatica may also be caused by a narrowing (stenosis) of the vertebral canal inside which is contained the spinal marrow. Some persons are simply born with a more narrow canal than normal, while in some other cases stenosis can appear later, in example caused by an arthritis.

There can also be an alteration of the spine, when a displacement of a vertebra in relation to the vertebrae below occurs (spondylolisthesis).
