Hi Raj, I believe that my ET diagnosis was incorrect, as my initial symptom was arm stiffness, that then developed into a tremor, that initially was an intention tremor , but soon became a resting tremor. I embraced the ET diagnosis as it was benign and didn't look any further. Now that I have done some research i realize that all of the things that made my ET atypical, the rigidity, unilateral tremor, resting tremor are indications of PD. At least now I know.
