Thank you for posting this. I also take propranolol for tremors but it doesn't work either. I have read about it and was actually going to do that ultrasound procedure. They do it at Barrow here in Phoenix. The reason I did not is because I have AFib and you could actually wind up with a bleed in your brain as well as doing a tube MRI is not my favorite thing to do at all. but I'm going to have a procedure done to take care of the AFib and possibly after that I might look into it. I'm not exactly sure where you are located but I know they have several different places that they can do that procedure. There have been several other studies that I am looking into for essential tremors. I basically like doing them to help others. so I wish you luck with that ultrasound treatment. and yes after a while there's nothing that will fix it. but the videos that I have seen it's miraculous what the ultrasound can do but they can only do one extremity at a time. which would be fine if at least one of my hands would work.
