I was diagnosed with Parkinson March of this year. My situation is very unusual, the only symptom I have is violent tremor in my right leg. None of the other typical symptoms. A DaTscan revealed low dopamine. Now I am also starting to have my right arm shake. I have been on different forms of carbidopa levodopa, Mirapex, and Amantadine. Absolutely nothing has help even slightly. I have this shaking none stop throughout the day and get very little sleep because I am waking up and the shaking is again very violent. I am beside myself and am hoping there is someone out there that has had the rare problem I have and gotten help.
