I'm pretty sure I have Dupuytrens contracture in my left hand. The tendon running to my middle finger is visibly raised running to a small lump. Started to notice it a couple of years ago. Basically, your fingers eventually start to curl in and you loose the ability to stretch and straighten them. I don't have any mobility issues yet but reading about it on the internet is alarming. I'm starting to develop a dull ache in the palm of my hand. Seems a lot of musicians end up not being able to play at all. Anybody have any experiences of this?
