Really interesting to see how many different things the word for today inspired! One of my collegue (when I worked in the office) had a similar issues with his hand. He was (and he is) an excellent piano player and he used to do some exercises to "help" that hand. When I met you at the steemfest I noticed your hand (just because hands are the first things I noticed when I meet a person for the first time ^_^) and I thought it was similar to the hand of my collegue.
