In reply to escalator: A few years older now unfortunately, not updated the profile for a while!
My grandfather on my mothers side had it, otherwise no other history that I know about. I think I'm just special in the family as I got all the recessive genes for hair colour etc! I am yet to meet any other females with it.
I first noticed the dupuytrens end of 2007 I think. At the time I was having issues with RSI and tendosynivitis (sp?) from using a laptop and laptop button mouse to do my PhD on. I wasn't climbing much at the time so I'm pretty certain the laptop was the trigger rather than climbing though.
The RSI stuff cleared up after a long break away from computers post PhD and the dupuytrens doesn't seem to be getting worse (or better). I don't think its particuarly bad though.
At the time the doctors didn't want to do anything about it unless it got a lot worse, and it hasn't, so I've just learnt to live with it. When I first noticed it I was really squeamish about it, it made me feel sick the thought of anyone touching it on my hand, even now I still don't like it being prodded, does anyone else have that??
