Hi, I wonder does my symptoms ring a bell with anyone that has been diagnosed . I have right arm tremor and right lower leg numbness. I am going for a Datscan on the 23rd of this month but I am worried. My right hand tremors are quite bad and I get a terrible electrical sensation in my forearm , it seems like a iron bar has been inserted in my arm it feels so stiff, but still it feels like it is twisting. This feeling seems to get worse if I lean over to lift something. Does anyone get similiar symptoms?
