other factors greatly increase the risk of physical injury.
Incorrect computer usage may lead to carpal tunnel syndrome,
tendonitis, tenosynovitis or other musculoskeletal disorders. The
following symptoms may appear in the hands, wrists, arms, shoulders,
neck or back:
• Numbness, or a burning or tingling sensation.
• Aching, soreness or tenderness.
• Pain, swelling or throbbing.
• Stiffness or tightness.
• Coldness or weakness.
If you have these symptoms, or any other recurring or persistent
discomfort and/or pain related to computer use, consult a physician
immediately and inform your company's health and safety department.
