Playing the piano with a fistula?

[kriatina]

Hello,
I would like to know if there are any pianists with a fistula? I am very concerned about loosing dexterity in my fingers
and concerned about my fingers becoming cold as this might also have an effect...
... I am also concerned about which arm to have the fistula fitted in.
My learning to play the piano was originally “only” thought as a new method of rehabilitation...
... to get my right arm, hand and fingers moving again after “my” stroke,
but it has developed to be my favourite hobby ever since...

I was born left handed but brought up in a right handed way, which has left me with both hands almost being ambidextrous...

Where on the arm and on which arm should I have the fistula fitted to remain able to continue playing the piano?
What do I have to take care of to keep everything going despite the fistula and oncoming dialysis?
What do I have to make sure of before having the fistula fitted?
How important is vein mapping? How can I avoid possible nerve damage?

Thanks from Kristina.
