This is how RSI builds up: by doing the same movements many timeswhether you click or wave your arm around.
The other day my mum’s friend complained of a dull but nagging pain in her right shoulder she’s had for ages and is seriously impairing quality of life for her, as well as her performance at work, which, in turn, is a source of constant friction with her boss. She blames it on working long hours on a computer (she is right-handed) as it hurts most when she is sitting at her desk, so she has to resort to painkillers (that are harmful to kidneys or stomach) almost every day.
