Have had it in BOTH hands for over a decade . I kiddingly call it my "rosary beads " in my palms .
I have no pain some very mild ache on rare occasion, BUT no contraction of the fingers . More of a PIA than a painful or debilitating thing . has absolutely NOT affected skiing , golf , tennis etc
Also known as " Viking's disease "
