Hi jenny1976 I hope they tell you what it is that is going on with the vibration and numbness. I had and MRI in August and it showed that it was normal but they only tested me for MS and tumors so you have to tell them exactly what you are feeling and ask if they will test for more than the basic MRI. I started my 3rd period yesterday and my vertigo and head vibration and tingling numbness is so bad today, I feel like I am losing my mind. I had to work all day in the freezing cold and it was so terrible I can't believe I made it through it. Please let us all know what they tell you. I am going back to my ear specialist tomorrow because of my vertigo and hopefully they can give me something or do some more tests to find out how to help me cause I don't want to live like this, it is so scary not having your balance and always feeling like everything is moving around you.Good luck on your MRI tomorrow!
