I have severe RSI in my right shoulder right down to my wrist from spending too much time at a laptop - its keeping me awake at night and its agony. I've changing my chair/desk combination but my physio told me to get an upright mouse -currently I'm working with my conventional mouse reprogrammed for my left hand but its frustrating as I am right handed. I have small hands and I'm wondering if anyone has any good equipment tips. Thanks!
