Even if you were a doctor, making a diagnosis upon reading a post is not good practice. It is easy to find subjects who did nothing else but the suspected activity develop RSI, so it is a weird claim to suspect it might not exist. For computers in particular, the "emacs pinky" is common knowledge, unless you'd think people suffer from collective hallucination (maybe a side-effect of emacs?). It is definitely a condition that improves with rest, even if not totally and over a long period (months rather than days). There is also some level of evidence that suggest that psychological factors have an influence (there are a few obvious potential links that would explain it, but I'm not familiar enough with the research).
