I have dupytren's Contracture, but I've also got something that nobody so far can diagnose. My left hand is always swollen and I can't curl my fingers in, like to make a fist. I can only curl them about half way. The pain is intense and seems to run thread like down my palm to the base. It is very life altering and starting in my right hand now. It's starting with the nodule in palm and now my little finger won't curl in. Very, very painful. I'm a licensed artist and was a musician. Can't play guitar even a little. I've seen 4 specialists and nothing. They just send me on.
