As a lifelong keyboard user, I've never had that problem.
Although, getting cramp in my fingers more now, which might well be due to RSI problems. Might be my age, but I'm discounting that (now being older and wiser!).
Biggest problem I've got is our dog.
Our computer is right beside the stairs, which doesn't have any railings, and you sit with your back to the stairs, using the stairs as a seat backrest. Our dog likes to sit far enough up the stairs that she can lick your ears. Yuck!
She knows she's got a captive audience; that I can't lift my hands or turn round (away from the screen).
