I have it too, Sooz, in my left hand. It runs in my family but I had no trouble until I started taking joint supplements for a bad hip. It took a lot of research before I made the connection and by that time I'd just about lost the ability to play. Stopped taking supplements and am now mostly recovered, left with only a non-painful bump in my palm. In pouring over research on the web I came across the micro-surgery being done by a few surgeons; started in Belgium/France I believe, but there are a few docs doing it in the states now, as well. Much, much less invasive...if this is something you've not come across yourself and are interested, let me know...I may still have a few bookmarks.
