You don't mention whether you had any wrist-ache/RSI when you were a (presumably regularly-or-at-least-frequently-playing) super-good violinist?

It's so long ago that I can't remember clearly whether I had any pain when I was actually playing, but I do know that after I gave up I used to get occasional days when my left wrist would ache all day even without me having done anything unusual with it recently. So I wasn't very surprised when that was the one to keel over first in the later RSI incident.
