Roberta, I had unilateral PD for about 6 yrs then got tremors on right side (not hand) My understanding is that this is what can happen as the disease progresses. 4 movement disorder specialists diaganosed me with PD and I have PET scan from UCLA which says I indeed have PD. The meds don't help me either. This last year and few mos I have gotten more symptoms, like difficulty speaking and swallowing. Bilateral DBS only helped tremors, altho my understanding is that it sometimes helps dystonia.. My hands are like paws - now that drives me nuts. It's hard to decide which sypmptom is worse -for my first yrs it was tremor. Also, I'm not exercising anymore, it's so painful and I used to urge veryone to exercise.
