Low Back Pain
Low back pain is a generalized complaint which encompasses at least 30 different conditions. It usually involves the lowest 2 lumbar vertebrae. It is estimated that over 75% of the population in industrialized societies will experience low back pain. Low back pain may be associated with family history, disease, muscle strain or poor posture. In young people, most low back pain is due to muscle strain and/or poor posture. In older individuals, low back pain may be a result of the degeneration of the shock absorbing discs separating the vertebrae of the spine. Occasionally, stress may be associated with spasms in the muscles of the back.
Symptoms for low back pain typically appear between the ages of 20 and 30. By age 45, many people will have had their first episode of low back pain. It is characterized by a decrease in the range of motion and muscle or joint soreness. The pain may radiate to the legs. Repeat episodes generally are more severe than the initial attack.
