Has anyone else experienced the feeling of vibrations down their spinal cord? It is driving me crazy! It is like the top of my head is touching a wall with a very large motor behind it and the vibrations from the motor travel from the top of my head all the way down my spine. Sometimes the vibrations extend down to the tip of my nose, the tip of my fingers and the tip of my toes. I am also having a pulsating roaring in my right ear that has not stopped for a month.
