I'm sorry for this distress, mully.  My own finger/hand troubles have been, thank goodness, mild and temporary, so I don't have any advice for you other than to stress that each of us is different, as are our personal medical issues, as are the doctors who treat us.  Thus, I applaud you for doing a lot of research on the problem and consulting closely with specialists and your teacher; I only caution you as to your query here.  Someone else's outcome from a given procedure has no actual bearing on what yours will be; a zillion factors will be different.
