Avoid staying in the same position for too long. If your work keeps you still for hours on end, try to take breaks and move around every 30 minutes or so. If some action causes pain, stop! Good posture for sitting, walking, running, lifting -- any activity, really -- can help, too. Use a firm, but not overly tight grip when you pick up heavy things, and avoid lifting with just one arm or only one side of the body.
