Bart,I have a question for you. If someone could accurately guarantee you that your symptoms would never get worse than they are now for the next 70 years, would you be able to live a comfortable and quality life? I ask this because I have some of the same symptoms you have described, including long bouts of back twitches, torso twitches, body tingling, tongue zaps, internal vibrations, etc.. These symptoms in and of themselves have pushed me to Klonopin which has brought some relief. My symptoms are as severe a problem as the worry about what is causing them and where they are leading. You need to be clear with yourself about the boat you are in. If your symptoms alone aren't interfering with your life and the problem is only anxiety, you must realize that the reassurance you seek is not available and is not available to anyone in the world. We are all human and subject to health problems that are out of our control. We all have to learn to keep that fact in proper perspective by doing what is reasonable to care for ourselves but otherwise enjoy the hear and now and deal with problems as they come rather than anticipating them. The choices are constant worry, fear, and misery and living in the moment with reasonable precautions. There is no better third choice so we must pick between the two available.If your symptoms are causing misery apart from anxiety, then you should actively work with your doctors to find some relief. Maybe a reduction in your symptoms will help with the anxiety since it will allow you to focus on other things and get better sleep. This is what it did for me.Krackersones
