I'm very clumsy on occasion and it's not the meds. I don't have RSD in my hands (yet) I don't think. I'm also very unsteady and fall a lot so balance may contribute in some instances. But I drop things all the time like pills and that's not a balance problem. My hands just won't grasp and hold right. Worse some times than others. I'll start doing something and I know I don't feel very coordinated but kind of plow through anyway. Sometimes it doesn't work out well. I just broke a still in warranty macbook pro by dropping it. That one hurt.
