What can cause low back injuries?
Many things can cause low back injuries, such as muscle strain or spasm, sprains of ligaments (which attach bone to bone), joint problems or a "slipped disk." The most common cause is using your back muscles in activities you're not used to, such as lifting heavy furniture or doing yard work. Unexpected events such as taking a fall or a car accident can also cause low back pain.
A slipped disk (also called a herniated disk) happens when a disk between the bones of the spine bulges and presses on nerves. This is often caused by twisting while lifting. Many people who have a slipped disk don't know what caused it. In most cases, slipped disks and other low back pain can be relieved by following a few simple methods.
