Mine wasn't severe, but it was there well enough to annoy me and make me concerned. I had it for about one or two years. Then I bought a Microsoft Natural Keyboard Pro and an ergonomic mouse and it went away so quickly (like, nearly instant), that I now believe, that what I once read may be true: That the reason for RSI may be psychosomatic. The interesting thing to note is, that I did not use an ergonomic keyboard/mouse in the last ten years and the RSI did not come back.
