Hi,

I reckon there *is* one way to decide whether any RSI/RSS/CTS is "true" or a form of RSD, and that is to ask yourself how much you've used the affected limb. In my case I'm quite surprised I didn't get RSI sooner, I use the mouse so much that my hand, by rights, should have fallen off by now, LOL. Overuse? Repetitive movement? If that doesn't factor into your medical history, then look elsewhere, if it does, then it's true RSI/RSS/CTS etc.

all the best!
