When I am driving the car down the interstate and just cruising along, my right foot (on my PD-affected right side) oscillates at about 0.5 Hz, squeezing and releasing the gas pedal. It was very subtle at first, then got so that my wife finally said it was driving her nuts and would I please use cruise control. I never did this before Parkinson's, but my neurologist says it's too slow a frequency for tremor. My right arm tremors, but much more quickly. Has anyone experienced this sort of thing?
