I'm sure it varies per individual. There are several factors that contribute to it as well. I guess it was worse on me from playing both piano and guitar. I just found out the other day that my old lead guitarists gave up his instrument after 40 something years of playing. It took a tole on his wrists. I feel really bad for him too. He was a hell of a guitarist. I do remember in our rehearsals he wore braces on his wrists. I don't play guitar nearly as often as I used to so I think my progression has slowed down a bit. Only problem is that playing guitar isn't like riding a bike I tried to get back on the other day and fell off a lot I now try my best to have good hand posture when playing on the keys. There are times where I stop because I'll get a sharp pain in my wrist and pinky finger.
