Causes of lumbar pain include overuse injuries, disc tear, vertebral fractures, spinal stenosis and scoliosis, according to WebMD. Other causes of lumbar pain include muscle strain, arthritis and skeletal irregularities, reports Mayo Clinic.
Spondylolisthesis is a condition that results in wear and tear of the joints and ligaments, inhibiting the normal position of the spine, says WebMD. Sometimes a vertebra can move more than it should and slide on top of another, triggering bones to press on the spinal nerves which causes lumbar pain.
Muscle or ligament strain can cause lumbar pain as a result of repeated heavy lifting or sudden unusual movement that may put a strain on the spinal ligaments or back muscles, notes Mayo Clinic. People who are in poor physical condition can suffer painful muscle spasms due to constant strain on their backs. Arthritis in the spine can affect the lower back and cause lumbar pain due to a condition known as spinal stenosis.
Abnormal spine curvatures can result in lumbar pain when an individual suffers from conditions such as lordosis, kyphosis and scoliosis, explains Healthline. These conditions mostly cause low back pain in children and teenagers. The pain results from the pressure on the vertebrae, tendons, muscles and ligaments, resulting in poor posture and lumbar pain.
