I think it was a combination of things @kmakm. My general condition improved and I was using my hands more, knitting, reading, just general up and abouting, but I have to say, I think it helped a lot. If nothing else, it worked as stress balls for me. Each squeeze, both with the dough in my palm, as well as pushing one finger at a time into the lump in my hand, helped me to squeeze out my anger and frustration at this whole shitfest. Then I found myself actually playing with the stuff...rolling it into little balls and snakes and then making little figures...actually was quite therapeutic for me. My grip is now good considering my finger joints are so totally stuffed from the scleroderma.
