Computer users may experience occasional discomfort in their hands, arms, shoulders, neck as well as other parts of body. If some one experiences symptoms such as recurring or persistent discomfort, pain, throbbing, aching, stiffness, burning sensation, tingling or numbness; should not ignore these warning signs. One should consult a qualified medical professional even if symptoms occur occasionally. Above cited symptoms can be associated with painful and sometimes permanently disabling injuries involving nerves, muscles or tendons. These computer associated musculoskeletal disorders (MSDs) include carpal tunnel syndrome, tendonitis, and tenosynovitis. Severity of symptoms depend on many factors like general physical & medical conditions of the computer user, daily duration of computer use, type and make of computer key board & mouse, type of monitor (CRT, TFT or LCD) and posture during computer operation. For guidelines to reduce the risk of developing an MSD, please refer to "Healthy Computing Guide". You can access the "Healthy Computing Guide" at www.microsoft.com/hardware/hcg/default.html .
