The causes of back pain include mechanical problems, spine injuries and acquired diseases, states WebMD. Tumors that appear in the back as a result of cancer and infections that involve vertabrae can also cause back pain.
Mechanical problems involve how the spine moves or how an individual feels when he moves the spine in particular ways, explains WebMD. One mechanical cause of back pain is intervertebral disc degeneration. This condition involves the deterioration of the discs located between the spine vertebrae. When these discs deteriorate with age, they lose their cushioning ability and cause back pain. Spasms, ruptured discs, muscle tensions and wearing down of facet joints also cause back pain.
Spine injuries that cause back pain include sprains and fractures, notes WebMD. Sprains occur when an individual improperly twists or lifts, tearing the ligaments that support the spine. Fractures are caused by osteoporosis, which is a condition that results in weak, porous bones. Severe injuries due to accidents and falls can also cause back pain.
Conditions and diseases such as scoliosis, spondylolisthesis, arthritis and spinal stenosis cause back pain, according to WebMD. Other conditions that can cause back pain include pregnancy, endometriosis, fibromyalgia and kidney stones.
Emotional stress can increase the severity and duration of back pain, explains WebMD. It can cause tension and pain in the back muscles.
