Lower left back pain is a frequent culprit of pain and is responsible for many visits to an orthopedic doctor.Back pain on the left side can be caused by a number of reasons like: Improper use of the back muscles lead to Lower Left Back Pain as a result of overuse related to repetitive lifting of heavy objects, or too much exercises can often lead to strained muscles in the left lower back. In addition obesity or poor posture can also place added weight and pressure on the lower back. If you sit on a chair for longer periods, where the left side of the back is under constant strain say in front of the computer can lead to Lower Back Pain.
Another serious cause of pain is the left side back pain is a herniated disc. In such a situation part of the disc begins to bulge and slide out into the spinal column. This alone can be very painful.
Lower Left Back Pain which is part of the larger lower back pain condition is on the increase .More serious causes of left side back pain can also be related to aging and wear and tear. Another reason 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 as in those days, people would keep shifting weight and position in their chairs to allow rest to the back. But now with computer monitors fixed in a particular position, there is little scope for adjusting your position and weight in your office chair. Just sitting in one particular position for hours together puts the lower back under a lot of strain. As a result,the back cannot take this constant strain on everyday basis. This initially leads to lower back stiffness and gradually the back starts getting painful.
