Back pain is one of the most common reasons people go to the doctor or miss work, and it is a leading cause of disability worldwide. Most people have back pain at least once.
Fortunately, you can take measures to prevent or relieve most back pain episodes. If prevention fails, simple home treatment and proper body mechanics often will heal your back within a few weeks and keep it functional. Surgery is rarely needed to treat back pain.
Back pain that comes on suddenly and lasts no more than six weeks (acute) can be caused by a fall or heavy lifting. Back pain that lasts more than three months (chronic) is less common than acute pain.
Back pain often develops without a cause that your doctor can identify with a test or an imaging study. Conditions commonly linked to back pain include:
Muscle or ligament strain. Repeated heavy lifting or a sudden awkward movement can strain back muscles and spinal ligaments. If you're in poor physical condition, constant strain on your back can cause painful muscle spasms.
Bulging or ruptured disks. Disks act as cushions between the bones (vertebrae) in your spine. The soft material inside a disk can bulge or rupture and press on a nerve. However, you can have a bulging or ruptured disk without back pain. Disk disease is often found incidentally when you have spine X-rays for some other reason.
Arthritis. Osteoarthritis can affect the lower back. In some cases, arthritis in the spine can lead to a narrowing of the space around the spinal cord, a condition called spinal stenosis.
Skeletal irregularities. A condition in which your spine curves to the side (scoliosis) also can lead to back pain, but generally not until middle age.
Osteoporosis. Your spine's vertebrae can develop compression fractures if your bones become porous and brittle.
Signs and symptoms of back pain can include:
Anyone can develop back pain, even children and teens. These factors might put you at greater risk of developing back pain:
