A common, painful condition affecting the lower part of the spine involving the muscles, nerves, or bones of the back.

Low back pain is caused by injury to a muscle (strain) or ligament (sprain). Common causes include improper lifting, poor posture, lack of regular exercise, a fracture, a ruptured disc or arthritis.

Often, the only symptom is pain in the lower back.

Most low back pain goes away on its own in two to four weeks. Physiotherapy and pain relievers can help. A few cases may require surgery.
