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.

The following section provides tips for more comfortable computer use.
