My mouse-use can't be the culprit - I'm usually on a laptop with a trackpoint and I also use a keyboard with a trackpoint with my machine at work too. I've been making a conscious effort to type with my wrists straight today and it's helped a little bit (memories of piano class when I was a wee lad).
an ergonomist would be the best person to consult to see if the way you work could promote an injury. see a chiropractor about the bone thing, see a sports doc if the chiropractor can't find anything. sports docs tend to be more on the cutting edge of repetitive strain injuries / connective tissue injuries than your average general practitioner.
i doubt it's your mouse - you have an intellimouse wireless explorer so between the shape of the mouse and the lack of tether it's not going to be forcing you into a damaging position. if anything probably the keyboard position. I'm not so sure the so called ergonomic keyboards are necessarily safer than all the other keyboards out there.
since you're a geek it bears mentioning that there are many other styles of keyboards out there besides the standard configuration and the typical ergonomic keyboard that may be to your liking.
but right now I'd be more inclined to think it's a nerve being impinged rather than an RSI. you would have noticed it over a long period of time otherwise. did you do anything to your hand or arm recently that might have knocked things out of whack? it happens more often than most people think, remember that the skeletal system is basically held together by soft tissue, which is in turn susceptible to imbalances and consequently things can get pulled out of place. I've blown out both hamstrings and torn a muscle in my lower back because of this fact. It's something that can happen no matter how well conditioned or flexible you are.
