Causes

Common factors that cause low back pain can include spinal joint dysfunction, lumbar sprain/strain, nerve irritation, lumbar radiculopathy, bony encroachment, and conditions of the bone and joints. Every one of these is considered here.

1. Spinal Joint Dysfunction

Spinal joint dysfunction is extremely usual and does not usually produce pain or other evident signs or symptoms. Spinal joint dysfunction, also called vertebral subluxation, takes place when spinal joints get jammed, locked-up, or lose their natural posture or motion and may also impact nervous system function. Spinal joint dysfunction brings about indicators like pain, muscle spasm, weakness, numbness, prickling and reduced body performance.

2. Lumbar strain

A lumbar strain is a stretch injury to the ligaments, tendons, and/or muscles of the lower back. The stretching incident results in incredibly small tears of varying degrees in these tissues. Lumbar strain is widely seen as one of the most typical causes of low back pain. The injury could happen as a result of unneccessary use, incorrect use, or trauma. Soft-tissue injury is frequently considered “acute” if it has been present for days to weeks and “chronic” if it lasts more than 3 months.

Lumbar strain most often happens in people in their 40s, nevertheless it may happen at all ages. The condition is described as localized discomfort in the low back region with onset following an event that mechanically stressed the lumbar tissues. The degree of the injury can vary from slight to serious, depending on the degree of tension and ensuing spasm of the muscles of the low back.

3. Nerve irritation

The nerves of the lumbar spine can be irritated by mechanical force (impingement) by bone or some other tissues, or from disease, somewhere along their paths — from their roots at the spinal cord or as they pass through muscles and around bones to their end point. These conditions involve lumbar disc disease, bony encroachment, as well as inflammation of the nerves triggered by a viral infection like shingles.

4. Lumbar radiculopathy

Lumbar radiculopathy is nerve irritation which is brought on by damage to the discs between the vertebrae. Damage to the disc happens as a result of acute traumatic injury (e.g. lifting a thing that could be too hefty) or due to degeneration (“wear and tear”) of the external ring of the intervertebral disc. Because of this, the central softer area of the disc may rupture (herniate) from the external ring of the disc and constrict or irritate the spinal cord or its nerves as they exit the bony spinal column.

This rupture is what causes the widely identified “sciatica” pain of a herniated disc that shoots from the low back and buttock down the leg. The pain commonly spikes with motion at the waist and might increase with coughing or sneezing.

5. Bony encroachment

Any sort of problem which brings about excessive or abnormal movement, or growth of the vertebrae of the lumbar spine could limit (encroachment) for the enclosed spinal cord and nerves. Good examples of bony encroachment of the spinal nerves include things like foraminal narrowing (thinning of the portal by which the spinal nerve leaves the spinal column), spondylolisthesis (slipping of one vertebra relative to another), and spinal stenosis (retention of the nerve roots or spinal cord by bony spurs or other soft tissues in the spinal canal). Spinal-nerve compression in these problems can bring about sciatica pain which radiates down the legs. Spinal stenosis can cause leg pains which worsen with walking and are relieved by resting (resembling the pains of bad circulation).

6. Bone and joint problems

Bone and joint issues that trigger low back pain include those pre-existing from birth (congenital), the ones that result from damage (degenerative) or injury, and those that result from inflammation of the joints (arthritis).

Congenital bone problems – Problems like scoliosis (sideways curvature of the spine) and spina bifida (spinal defect).

Degenerative bone and joint problems — As we get older, the water as well as protein content of the body’s cartilage alters. This transformation brings about weaker, thinner, and much more delicate cartilage. Because both discs and the joints which stack the vertebrae (facet joints) are partially composed of cartilage, these areas are subject to damage as time passes (degenerative changes).

Injury to the bones as well as joints — Fractures (breakage of bone) of the lumbar spine as well as sacrum bone typically impact elderly people with osteoporosis, particularly those who have taken long-term cortisone medicine.

Arthritis — The spondyloarthropathies are inflammatory types of arthritis that can impact the lower back as well as sacroiliac joints. For example reactive arthritis (Reiter’s disease), ankylosing spondylitis, psoriatic arthritis, and the arthritis of inflammatory bowel disease. Each of these diseases can result in low back pain and stiffness, which is usually worse in the morning. These problems usually begin in the second and third decades of life.
