Mine started out on the right involving first my right hand then my right leg. I got really nervous (poor choice of words) when I noticed my left leg getting into the act. However what happened was I got a terrible tremor in both my legs but the tremor in my upper body disappeared completely for 8+ years. Just recently it has reappeared in my right hand/arm. But if my arm kicks in my legs often stop. At any given time I only have two limbs involved with tremor. It's a bit of a lottery to guess which two it will be today. Welcome to "Wonderland" ....that's the place we all stand around and wonder what the hecks going on here anyway????
