Lower Left Back Pain is common among people and can be caused by a number of reasons. Improper use of the back muscles lead to Lower Left Back Pain. If you sit on a chair for longer periods, say in front of the computer, poor posturing, where the left side of the back is under constant strain, can lead to Lower Back Pain.
Lower Left Back Pain is part of the larger lower back pain condition, which affects people mostly. The reason why the back suffers can be attributed to our sedentary life style. An office job in the pre-computer era was not as strenuous for the back as it is now. In those days, people would keep shifting weight and position in their chairs to allow rest to the back. Now with computer monitors fixed in a particular position, there is little scope for adjusting your position and weight in your office chair. Sitting in one particular position for hours together puts the lower back under a lot of strain. The back cannot take this constant strain on everyday basis. This initially leads to lower back stiffness and gradually the back starts getting painful.
The lower back cushions the weight of the upper body, and it acts as a shock absorber to reduce the impact of walking and running. Joggers, who jog on cemented tracks or on roads, expose their backs to greater risk of injury because of higher intensity of shock. Lower Left Back Pain can start with injury to the left leg, hip or back. The muscles, tendons, ligaments, joints, nerves, discs and bones are under constant strain when we are mobile. Our turning, twisting and bending movements also put the lower back under strain. Regular back stretching and strengthening exercises will keep your back supple and strong.
Infection of the left kidney and the sciatica nerve of the left leg can also cause Lower Left Back Pain. If you experience sharp pains in the left side of the back, consult a physician to diagnose your condition.
