:( Been there :( Use your braces, there are so many different ones that I think I still have 3 or 4. the one that is like a foam sleeve with laces is the one that helped me most during sewing. But, I still had to have surgery on both hands........It has been several years, and yes, I still have some problems, but that was because I waited so long that so much damage was not repairable.
I have fibromyalgia and arthritis, too. So the triple threat makes even typing in the forum difficult.
Good luck, but I would get a good hand surgeon and go for it. :|
