What causes back pain?

Back pain is caused by a number of factors. It can result from an injury, spinal degeneration, repetitive sports- or work-related injury, arthritis or a developmental defect like scoliosis. Other conditions that cause back pain include injuring a muscle, tendon, or ligament in your lower back; a rupturing or bulging of a disc between your vertebrae; arthritis or other disc problems; lumbar facet joint syndrome; inflammation of your sacroiliac joint, which joins your hip to your spine; sciatica, which is a result of herniated discs or spinal stenosis; and cervical radiculopathy, which is having a “pinched nerve” in the neck that can cause numbness, weakness and pain.
