Muscle pain: Rsi is an acronym for repetitive stain injury, and goes by numerous other names. It is associated with a variety of musculoskeletal complaints that may be arise from repetitive tasks, forceful exertions, vibrations, mechanical compression (pressing against hard surfaces), or sustained or awkward positions. The first sign is typically pain that increases with activity.

Repetitive stress: If you are referring to REPETITIVE STRESS INDEX OR SYNDROME, the signs might be pain, aching, twitches, some numbness, etc. I would see a Dr. before it becomes unmanageable.
