I think it's great you push yourself to drive. I would try the special handle too except I can't close my fingers all the way or bend my wrist and when I did try holding my rsd arm up for a long time, it started to hurt more than it already does since I also have limited range of motion in my shoulder also because of my rsd. I also can't drive with my meds and I can't drive without them. So I just don't drive anymore. I don't think at least for me it's a responsible thing to do. My pm dr also said that I shouldn't use my rsd hand to hold the steering wheel, because of concern of it getting twisted and crushed if I were in a car accident. If that happened rsd spread is more likely to occur. He suggested not driving if I could help it because of this.
