I believe I have Essential Tremors and have had for about five years, steadily getting worse. In the past few months, my vision is off. Best way to describe it is that print is a bit blurry. I have also had headaches in the back of my head almost daily for several months. Also, there is unrelenting pressure in my upper teeth which has been going on also for about five years. I know my tremors are both external and internal. Any possible links between tremors, vision, headaches and pressure in teeth?
