Causes of Lower Back Pain
Spinal degeneration from disc wear and tear can lead to a narrowing of the spinal canal. A person with spinal degeneration may experience stiffness in the back upon awakening or feel pain after walking or standing for a long time.
Spinal stenosis related to congenital narrowing of the bony canal predisposes some people to lower back pain related to disc disease.
Osteoporosis is a metabolic bone disease marked by progressive decrease in bone density and strength. Fracture of brittle, porous bones in the spine and hips results when the body fails to produce new bone and/or absorbs too much existing bone. Women are four times more likely than men to develop osteoporosis, and Caucasian women of northern European heritage are at the highest risk of developing this condition.
Skeletal irregularities produce strain on the vertebrae and supporting muscles, tendons, ligaments, and tissues supported by the spinal column. These irregularities include:
- Scoliosis, a curving of the spine to the side
- Kyphosis, in which the normal curve of the upper back is severely rounded
- Lordosis, an abnormally accentuated arch in the lower back
- Back extension, a bending backward of the spine
- Back flexion, in which the spine bends forward.
Fibromyalgia is a chronic disorder characterized by widespread:
- Musculoskeletal pain
- Multiple "tender points," particularly in the neck, spine, shoulders, and hips
- Sleep disturbances
- Morning stiffness
