Lower back pain occurs to nearly everyone sometime in life. While most lower back pain lasts only a few days, acute or chronic back pain poses a serious health issue for many people.
The back is supported by the spinal column, which is composed of the spinal cord and the surrounding vertebrae. The spinal column is linked by muscles, ligaments, and tendons. The vertebrae are held together by flexible discs which allow it to bend and change position. The spinal cord is connected to a network of nerves from between each vertebrae to the whole body and senses movement, or any pain. download Guide PDF
