I have been diagnosed with ET. My father also has ET so I am guess I get it from him. It came on right before I turned 40. The question I has any one experienced this? Just recently (maybe im just noticing it) when my thumb starts to tremor and I put my hand at rest ex in my lap it takes up to 20 secs for my thumb to stop with the tremor. It also stops if I support it with my hand. Then it will stay still until I move my hand again. Also this is intermittent (seems it never does it when I want to show somebody). This new tremor is kinda stressing me out because 1. it is new 2. I don’t know if it would be something besides ET.
