I never could make me fingers stay still for some reason. It's always shaking at the tip of my fingers, sometimes even my hand are shaking. I don't notice me being nervous or anything. It just happens at random times, like it happens when I watch TV or any other times. I just think something's is wrong for my hands not to be steady. I'm 13 and I don't have any sickness or whatever. Please let me know what that is. Thanks
