hi...just wanted to say I was where you are at now. I also have essential tremor which started in my hands, right worse than left and then moved into my head and neck. It was misdiagnosed as anxiety for about 7 years, then I was treated with multiple medications over the next 10 years. When the medications quit working, I was referred to a neurosurgeon that performed DBS surgery and guess what? It was very successful!! I am able to do alot of things I haven't been able to do in years. I feel like a new person. I just want to say, don't give up and find a good neurologist to handle this disorder, ask questions, try all the meds first. There is hope.
