The source of back pain can be from a wide variety of structures, including muscles and ligaments, intervertebral discs, joints, or nerves. In addition to being extremely painful, back injuries can lead to long-term problems if not treated correctly. In some cases, lower back pain may also have an emotional component due to the impact on quality of life. Back pain sufferers often experience depression and anxiety along with poor sleep patterns that could potentially lead to insomnia. This has a ripple effect on daily activities and family relationships.
