Back Pain
Definition
The spine is a column of bones held together by muscles, tendons and ligaments. The spinal bones are cushioned by shock-absorbing disks. A problem in any part of the spine can cause back pain. For some people, back pain is simply an annoyance. For others, it can be excruciating and disabling. Most back pain, even serious back pain, goes away on its own within six weeks. Surgery usually isn't suggested for back pain. Generally, surgery is considered only if other treatments aren't effective. If back pain occurs after trauma, call 911 or emergency medical assistance.
Causes
Back pain may be caused by mechanical or structural changes in the spine, inflammatory conditions, or other medical conditions. A common cause of back pain is injury to a muscle or ligament. These strains and sprains can occur for many reasons, including improper lifting, poor posture and lack of regular exercise. Being overweight may increase the risk of back strains and sprains. Back pain also may be caused by more-serious injuries, such as a spinal fracture or ruptured disk. Back pain also can result from arthritis and other age-related changes in the spine. Certain infections can cause back pain. Possible causes of back pain include: Mechanical or structural problems Herniated disk Muscle strains (An injury to a muscle or to tissue that connects muscles to bones, called a tendon.) Osteoarthritis (the most common type of arthritis) Scoliosis Spinal fractures Spondylolisthesis (when spinal bones slip out of place) Sprains (Stretching or tearing of a tissue band called a ligament, which connects two bones together in a joint.) Inflammatory conditions Ankylosing spondylitis Sacroiliitis Other medical conditions Endometriosis — when tissue that's similar to the tissue that lines the uterus grows outside the uterus. Fibromyalgia Kidney infection (also called pyelonephritis) Kidney stones (Hard buildups of minerals and salt that form inside the kidneys.) Obesity Osteomyelitis (an infection in a bone) Osteoporosis Poor posture Pregnancy Sciatica (Pain that travels along the path of a nerve that runs from the lower back down to each leg.)
