Sitting slumped in a chair position which produces continual strain on your lower back Any recurring strain put on your back, however mild the strain may be Chronic trauma occurs in most of our daily lives many times during each day, day after day. The cumulative effects of chronic trauma eventually reach a point at which the back is no longer capable of withstanding them. This is the point when pain occurs. Psychological stress may also cause back pain. An individual develops pain in his back as a defense mechanism in a situation in which he finds he can no longer cope with emotional difficulties.
Back pain can be part of aging when the discs between the spinal vertebrae deteriorate.
The first reason concerns our discs. During the first 15 to 20 years of life, blood circulates through these tough, flexible shock absorbers that fit between the bones of our spine. During in those twenty years, the discs are in their prime. However, after early adulthood, the blood supply to the disc gradually stops. Every action of day to day life, like walking, sleeping, and lifting etc. is done properly then back pain can be avoided.
