If you do work which places a strain on one side of the body, you may experience fatigue, tenderness, pain, swelling and stiffness in the muscles, tendons and joints in the long or the short term. It may also impair your capacity, result in a lack of attention and increase your risk of accidents. Injuries to the neck, shoulders, arms and hands are often seen, but all parts of the body may be affected. Monotonous work that places a strain on your body can also impair your quality of life.
