The back includes the bones of the spine ( vertebrae that support body weight), their joints, the discs that separate the vertebrae and absorb shock as you move, and the muscles and ligaments that hold it all together.
Back pain occurs when one or more of these structures is injured. Back pain can also occur when you sprain or strain the ligaments or muscles from a sudden or improper movement or due to overuse. If you damage your discs so that they tear or stretch and the tear is large enough, the disc may press against a nerve, the irritated nerve may swell or become inflamed thereby causing back pain.
