If you work at a computer all day, your upper back and shoulder pain may simply be your sitting posture – leaning into the screen. Ergonomics! Start by getting a good chair and a pair of glasses that allow you to see the screen while sitting up straight. If your pelvis is not symmetrical, you may have to use a thin pillow under one bun, to raise it.
An unstable pelvis caused by physical or functional leg length discrepancies will also impact the scoliotic (lateral) curves of your spine. You may be raising one hip and the opposite shoulder causing constant muscle tension.
Sitting posture is impacted by your feet, and by your normal standing posture. If you have a slouching standing posture you’ll probably have a slouching sitting posture. If you sit with your feet flat on the floor under your knees, the rotation of your pelvis is impacted, and you might just find yourself in a little more erect posture. If you are accustomed to an erect posture while standing and walking, chances are that you will have a much higher degree of subconscious awareness of your sitting posture, and you will (subconsciously) correct it. Wear Posture Control Insoles® to improve your standing and walking posture.
