I have almost imperceptible tremors in my right thigh. I cannot feel them with my hand, but I can feel them in my body - i.e., I sense them, but when I put my hand on the back of my thigh, I cannot feel anything. This has been going on for a couple of days, almost constantly. It does not affect me in any other way - no weakness in my legs, no discomfort, just a sensation like I am on a vibrating platform (like when the subway comes into the station).
