Repetitive Stress Injury is also known as, repetitive strain injury, work related upper limb disorder (WRULD), and occupational overuse syndrome.Risk factors include an ergonomically unsound work station, poor posture, and excessive workload. Symptoms may accumulate over long periods of time and include recurring sharp or dull pain, soreness, stiffness, tingling and numbness, loss of sensation, limited range of motion, weakness, fatigue, or persistent tension in the neck, shoulders, upper back, elbows, wrists, or hands.

A slipped disk does not really slip; the tough outer fibrous ring (annulus) cracks open and the softer inner layer protrudes (prolapse) through the crack, like toothpaste coming out through a crack in a toothpaste tube. For this reason doctors prefer to speak of a disk prolapse rather than a slipped disk.
