Many people who use a mouse suffer from soreness in the hand, wrist, elbow, shoulder or neck. No immediate solution exists. However, most ergonomists agree that the design and position of the mouse, the position of your body, and the way you use the mouse may contribute to your risk of injury.
Time is the main culprit of injuries from the computer mouse.
If you're unable to position the mouse where you'd like to because the keyboard is in the way, consider separating mouse tasks from keyboard tasks. Learn keystroke combinations, macros and any other functions that can replace double-clicking and dragging the mouse. Don t start a job at the last minute. When you're on a tight deadline, your muscles will naturally tense up, and you might forget to relax your hand or readjust your position as necessary. Keep the desk clean and uncluttered.
