Muscle stretch and strain on the ligaments as a cause of severe back pain:
Some of the largest, hardest working muscles in the body are in or near the lower back such as Transversospinalis muscles, Erector spinae muscles, Latissmus Dorsi, Quadratus Lumborum; they work with all might, even with simple activities. On account of the substantial challenges put on them, these muscles are one of the most common causes of low back pain.
Lifting massive weights or unanticipated unfolding or stretching or spasms can tighten and lacerate the lower back muscles or ligaments; the result is severe back pain.
The obesity factor:
Low-grade physical fitness, obesity and gross weight problems all contribute to severe back pain by putting unvarying stress on the back.
Chronic diseases such as arthritis of the intervertebral joints may become a source of severe back pain.
Degenerative joint disease:
The firm, rubbery smooth tissue that lines the intervertebral joints and shields the bones at the joints is known as cartilage; it gets eroded, with aging leaving the bones to rub on each other instead of moving smoothly over one another. This degenerative process of the joints is known as Osteoarthritis.
A rift in the intervertebral discs takes place, when its outer layer tears. With the process of aging, the jelly-like substance becomes desiccated and the discs distend and burst. Even minimal compression, on the spinal cord could result in severe back pain with a feeling of pins and needles or insensibility.
Spinal stenosis is the restriction of the spinal column that causes heaviness on the spinal cord.
Spondylolisthesis is a condition in which a vertebra in the spine slips out of the proper position onto the bone below it. This condition which is quite common in aged people and a cause of severe back pain.
Spondylolysis is a defect of the lumbar vertebra in the spinal column. It is caused by stress fracture of the bone, and is common in youth and teen-agers, who over-exert in movements and sustain recurrent anguish to the lumbar spine, hence severe back pain.
Osteoporosis is a bone disorder characterized by a reduction in bone density, accompanied by increasing porosity and brittleness found chiefly in women who have passed menopause. . Osteoporosis increases the hazard of fracture of vertebrae and hence severe back pain.
Inflammatory arthritis of the lower back
Sacroiliitis and spondylitis (swelling of the joints between the vertebrae) may cause severe back pain.
A malignancy could either commence in the structures of the lower back, or might metastasize from the breast, prostate gland, lung or kidney to the vertebrae and cause severe back pain.
Bacterial infections of the bones or discs can cause severe back pain as a result of soiling established a lesion or during an orthopedic surgery.
* Kidney stones housed in the ureter
* Uterine fibroids
* Back pain during pregnancy
* Aortic aneurysm
* Rupture of aorta
All the above-mentioned conditions could cause severe back pain.
