Whenyou sit, stand up, bend or twist, large compressive forces are applied to your spine. There are several factors that determine the ability of your inter-vertebral discs to handle these forces: your inherited make-up disc health -- worsened by smoking, poor nutrition, sedentary lifestyle, weak muscles, and obesity ageing poor posture -- while sitting, standing and lifting heavy loads during home, work or sporting activities. DISC INJURY When the forces applied to your neck exceed the strength of your discs, minor injuries to the disc can occur. It is important to note these injuries may or may not hurt at the time they occur.
